------------------------------
Subject: 5.1. What is TAPI?
Telephony Application Programming Interface. This cool piece of
Windows 95 lets you use modems and other communication devices easier.
Under TAPI, it's possible to change devices, for example, and not have
to re-configure every piece of software to work with it. You can set
up a single set of dialing rules, or multiple dialing rules based on
your location, and the apps are smart enough to dial long distance as
required. You can run a modem answering program, and quickly dial out
or send a fax without having to shut down the answering program.
I really like TAPI because of cool features like that. Microsoft
extended TAPI to include SmartRing (TM) compatibility and voice
capability in UNIMODEM V, available with the Win95 Service Pack. Super
cool.
------------------------------
Subject: 5.2. How do I use my modem with Win95 apps?
Install a "modem driver" first. To do this, run Control Panel/Modems
and have it look for your modem. Win95 will then send "AT" to all the
COM ports and look for an "OK" response. It will then query the
modem's I registers to try to identify it. Then it picks an
appropriate driver and asks you to confirm it, and gives you a chance
to change it, or replace it with one from a disk. When all this
finishes, a new "Modems" class of devices will appear in Device
Manager.
I use "driver" in quotes because the modem really doesn't need a piece
of program code unique to it. I refer to a "modem driver" as the .INF
file which describes how to communicate to the modem. Most standard
data and fax modems only require this info file. Non-standard modems
and voice modems installed via UNIMODEM V, however, will add extra
software, libraries, and executables. In this case, "driver" really
refers to extra software.
Finally, if this is the very first time a modem found its way into
your computer, Win95 will ask you about your location (what country,
what area code, any special codes needed to get to an outside line,
etc). One thing: If you live in North America and you DON'T live in
the United States, PLEASE pick a different country besides "United
States of America". Pick your appropriate country. Sometimes, when you
install a PnP modem for the first time it doesn't let you define your
location, so go to Control Panel / Modems and set your location.
Now that you have the modem available, run any Win95 application that
uses modems. For a quickie test, run HyperTerminal, which comes with
Win95. Immediately, this program asks you for a connection name, and
the modem you wish to connect with (If you have multiple modems, you
may pick one from the list). For this quickie test, when the "Dial"
requester comes up, just hit "Cancel". This goes to the terminal
screen where you can type "AT" yourself and expect an "OK" response.
If this works, great. You can then try calling your local BBS by
feeding its number to the connection setup and having it dial.
You probably noticed cool buttons like "Calling from:", "Dial
Properties", and the like. I get into all this cool stuff in the next
sections.
------------------------------
Subject: 5.3. How can I get an outside line in my office phone system?
This is the obvious thing to want if you use Win95 from your office.
Run Control Panel/Modems, hit Dialing Properties, and check out the
"To access an outside line" boxes. Type in the appropriate keys you'd
normally press on your phone's keypad into these boxes. Insert a comma
after this code to insert a five second pause. For example, "9," dials
nine then waits five seconds before dialing the outside number.
Remember that "," because you need to let your phone system switch to
an outside line before you start dialing. The "," is typically a five
second pause but this may vary depending on the modem type.
If you have a unique code for dialing long distance in your office,
you can put it in there, but don't include the standard "1" because
TAPI does this already.
All Win95 modem apps will use this rule as soon as you OK it.
------------------------------
Subject: 5.4. How can I dial long distance?
Thanks to Wouter Pinkhof for verifying these rules in Belgum; they do
work outside of North America.
You probably noticed an area code box in the phone number requesters
you get in Win95 modem apps. Normally the apps insert your current
area code (the area code for your current location). To make the
program dial long distance, change the area code. Also make sure you
have "Use country code and area code" if the program has such a
switch. The app will automatically insert the "1" (or whatever your
country code is) and any pre-dial instructions needed to get to an
outside line.
If the number you're dialing is long distance but in the same area
code, use the program's "Dial as a long distance call" switch.
HyperTerminal, Dial-up networking, and WinFax Pro 7.0 have switches
like this. Other programs such as MS Fax let you do this in the
person's phone number entry (with a switch like "Dial area code even
though it's the same as mine") or set long distance rules by dial
prefix. How a program dials long distance for same-area-code numbers
depends on the program.
* 5.4.1. Why is my computer dialing long distance when I know it's a
local number?
Maybe you have the "Dial area code" or "Dial as a long distance
number" switch turned on for that connection or number. Check with the
app's manual for setting this switch. If you're dialing a local
number, make sure you turn off this switch.
You might've used a different area code in your dialing location than
in the number you're dialing. Check to see that the area codes match.
This is the only way that Win95 knows how to distinguish a long
distance call from a local one.
Also, and this is quite common in Canada, maybe you specified "United
States" as your country, either in your location properties or in the
number itself. Set the country appropriately. If the country is
different, even if the country code and area code are the same, it
will try to dial the number as long distance. Apparently, 4.00.950B
will catch this mistake (as long as the country code matches, not
necessarily the country NAME).
* 5.4.2. How can I use my phone company's calling card?
Bring up dialing properties again, and hit the switch saying "Use
calling card". Then hit the "Calling card..." button. In the US and
Canada, the most common is "Calling card via zero" but Win95 comes
with calling card settings for most of the major long distance
carriers. The calling card setting is great if you're dialing from
work, but you don't want to cost the company for your personal calls.
Calling card settings are part of your dialing location, and each
location may use a different calling card setup. This is great for
notebook users who may plug into a hotel's phone system, or a branch
office's system, or a customer's system so you don't make the customer
pay for your phone call.
* 5.4.2.1. What if the card isn't from AT&T or Bell Canada?
A lot of weird long distance companies came out of the woodwork up
here in Canada, and many of them have bizarre calling card setups. To
create a card setup for your long distance company, first figure out
what you'd have to do to dial the number normally (like dial an (800)
number or something, followed by a user code, followed by the number,
or whatever) including the length of time between blocks of numbers.
Then in the Calling Card requester from the last section, hit
"New...". Give this new card a name.
Now you'll get three text fields to insert your dialing rules.
Right-click on one of them and hit "What's this..." to get a list of
commands you can insert into these boxes. Without a special dialing
sequence (IE: Direct Dial), the defaults for these would be:
Local Calls: G
Long Distance Calls: 1FG (This'll be "EFG" outside of North America)
International Calls: 011EFG (the "011" may be different outside of NA)
The "G" is the local number, the "F" is the area code, and the "E" is
a country code. The other keys you can use include dialable digits
(including the * and # keys), commas for pauses, a calling card number
itself, and so on and so on.
Use this basic sequence and insert the extra keys you need to press.
For example, to dial long distance calls with a calling card via zero,
you would replace the "1" in the long distance rule with a "0", then
after the "G" you insert some pauses and then the calling card number.
Right-click on any of these boxes and hit "What's this" to get a list
of valid keys you can insert into these boxes.
Finally when you're satisfied, hit "OK" to save the card. You can go
back and edit this calling card later.
If the long distance company uses voice prompts, be extra sure to
include pauses for the duration of the voice prompts. Use commas ","
to insert five second pauses. Also, if you normally get a "Thank-you"
message at the end, insert pauses at the end so the modem doesn't try
to recognize it as a voice answer and hang up on you.
* 5.4.3. Why isn't my computer dialing the area code for long
distance within my area code?
Don't forget to tell the program that this number is a long distance
number. Again, this varies between programs. When you tell the program
it's a long distance number, it will use the long distance dialing
rule instead of the local rule. MS Fax can do this by number prefix;
other programs let you do this per-number.
It's also possible you have a pre-release of Windows 95. Some early
versions would only just dial the "1" followed by the number, without
inserting the area code. If you get this symptom, you might have a
pre-release, developer's, or other bogus copy of Win95. Get your disks
or CD replaced and re-install Win95 to fix this. Apps call on TAPI.DLL
or TAPI32.DLL to generate the string of digits.
If you have to use this broken copy of Win95, you can fake your own
area code so it's different than the number you're dialing, and then
the app will insert the area code. I don't recommend this kluge at
all; you should replace your Win95 copy as soon as you can.
* 5.4.4. Why do I have to give the area code for local numbers?
This is so the app (and TAPI.DLL) knows not to insert the "1" and area
code before the number. Apps will automatically insert your current
location's area code for you, so normally you don't have to worry
about this.
If you need to dial long distance within your area code, tell the app
that the number is a long distance number, and it will insert the "1"
and area code for you. Proper Win95 programs offer a "Dial as long
distance number" option for this.
* 5.4.5. I don't live in North America. How does this area code
nonsense affect me?
To use all this advice and work outside of North America, swap the "1"
with your country code, and "Area Code" with your city code. Otherwise
all the same rules apply. Again, thanks to Wouter Pinkhof and Vu Tien
Khang for input here.
In Calling Card setups you may have to be especially careful with the
country code. Substitute the "1" for your country code, or just use
"E" which uses your target's country code.
Ten-digit dialing rules may apply in Eurpoean countries (France is one
example). Read section 5.7 below for suggestions.
Previous versions of this FAQ mentioned the need to insert leading
zeroes for "area codes" shorter than three digits; this is not
necessary.
------------------------------
Subject: 5.5. I have a notebook computer and I travel. How do I set up different locations and dialing rules?
To create a new location, go to that Dialing Properties screen and hit
"New location". Many TAPI apps provide a Dialing Properties button
which opens your location's properties. Each new location can have its
own area code, country code, dial-out access rules, even calling
cards. Be sure to set each of these when you create a new location.
This is pretty cool because you can keep the number entries themselves
the same, and TAPI knows to use different dialing rules depending on
your location.
Apps will let you pick your dialing location just before you dial your
number. When you swap locations the digit string will change to
reflect your current location. The one exception is MS Fax, which asks
you for your location when you run the New Fax Wizard.
------------------------------
Subject: 5.6. How can I turn off the annoying call waiting beep that cuts me off?
To turn off call waiting for the duration of this call, bring up your
dialing properties and turn on "This location has Call Waiting, to
disable it dial..." and type the string needed to disable call
waiting. The drop-down list gives many variations of "*70" to choose
from. Most tone-dial systems use *70, and most pulse dial systems will
use 1170.
------------------------------
Subject: 5.7. My local phone company makes me dial the area code for local numbers. How can I do that?
I heard of some American communities that make you dial "204 555-1212"
(without the "1") to dial the local number "555-1212" for example.
Win95 doesn't support this right out of the box, but you can set up a
bogus "calling card" to enforce this ten-digit-dialing rule.
In your location properties, turn on "Dial using calling card..." and
hit "New" to make a new calling card. Use these dialing rules:
Local Calls: FG
Long Distance Calls: 1FG
International Calls: 011EFG
The "FG" in the local calls rule will insert the area code for all
local calls.
MS has other ten-digit-dialing suggestions in KB article Q129049,
but this one keeps the rest of the TAPI benefits, like turning off
call waiting, or using dial prefixes to get to outside lines, or using
third party calling cards.
------------------------------
Subject: 5.8. Top ten dialing mis-conceptions
10. Win95 doesn't let me use my special calling card (Just make up a
new card)
9. WinFax Pro 7.0 doesn't use Win95 dialing rules (Yes it does; you
just have to MAKE IT use them. See the WinFax Pro 7.0 manual for how
to tell WinFax to use "Windows dialing".)
8. Win95 won't do ten-digit-dialing (Make up a "calling card" with
ten-digit-dialing rules)
7. I can't use my office phone system to dial out (Well, that depends
on your office policies!)
6. Call Waiting keeps cutting me off (Just tell Win95 to disable it in
location properties)
5. MS Fax won't dial long distance within my area code (Make an
address book entry with "Dial area code" turned on)
4. It keeps trying to dial long distance (get your country settings
right)
3. Dialing rules are a complete waste of time (Really? Would you
rather configure each of your programs separately?)
2. TAPI sucks. (not.)
1. TAPI sucks. (Really, this is both the top two mis-conceptions at
the same time!)
------------------------------
Subject: 5.9. Programs that answer the phone...
TAPI works both ways. Programs that dial out don't access the COM
ports directly, rather they access a TAPI device which communicates on
behalf of the COM port.
This logic applies to answering programs too. Really, it's TAPI that
detects the ring, then alerts the answering program and then that
program communicates via TAPI to pick up the phone and start
communicating. This has nothing to do with apps talking to COM ports.
These answering programs follow this logic (and perhaps others too):
* MS Fax
* MS Plus! dial-up server
* WinFax Pro 7.0
* pcAnywhere32
* 5.9.1. Can I dial out while some other program is waiting to
answer?
Because the answering programs communicate via TAPI, an outside
program can jump in and use the TAPI device without the answering
program even knowing about it. It's waiting for a signal from TAPI to
answer the phone, and that won't happen while the other program's
using the modem.
* 5.9.2. How do I run several answering programs at once?
Only the newest class of modems (the voice modems) can do this. To do
this, obtain one such voice modem, and download UNIMODEM V from
Microsoft's web site.
Once you installed all this, a little applet called "Operator Agent"
will invoke the appropriate app to answer the phone. Because the apps
themselves are waiting for TAPI signals, rather than signals from the
COM port itself, Operator Agent can signal the appropriate app
depending on the caller's response to its prompts. The Agent does its
job by sending a voice message to the caller, asking them to press a
key from 1 to 3 for voice, fax, or data. It then alerts the
appropriate program.
Alternately, you can use Distinctive Ring. If your modem supports
SmartRing (USR's Vi, Compaq's Presario modems, and IBM's MWAVE are
some SmartRing capable modems) and you have more than one phone number
for your phone line, you can configure what kind of program answers
what kind of ring. Bring up the Modems control panel and bring up
properties for your modem. You'll notice two new tabs (if your modem
supports them): "Distinctive Ring", and "Call Forwarding".
* Distinctive Ring lets you specify what kind of program (either
Voice, Fax, or Data) answers a particular ring. The ring choices
may be as simple as "one ring, two rings, three rings", or may use
a kind of Morse Code (with intermixed long & short rings if your
modem supports that). Once you specified what ring goes with what
kind of app, OK it, then launch your answering apps. NOTE: TAPI
apps identify themselves as one of these three kinds of programs
when they open a TAPI port, so you don't need to worry, for
example, if you replace MS Fax with WinFax Pro 7.0.
* Call Forwarding lets you forward calls to a different number when
you dial out using a TAPI dial-out client (HyperTerminal, or for
sending a fax, or for Dial-up Networking). Specify here what kind
of code you use to forward your calls, and hit OK. The system will
issue the call forwarding command when you dial-out, and undo it
when you disconnect.
The Distinctive Ring options won't kick in until you launch more than
one kind of answering program. However, they don't require an external
applet to monitor the phone line with.
* 5.9.3. You mean I can have a terminal server, fax receiver, AND a
voice mail receiver running all at once?
Yes. Depending on the kind of call, determined by Operator or
SmartRing, TAPI will alert the correct program.
NOTE: This is an interesting bug in UNIMODEM V. If you use Operator or
SmartRing without running some kind of voice message app, the system
will patiently wait for a voice messaging app to answer the phone. In
fact, it will wait forever (or at least until you try to dial-out,
then it will reset the "Ring Monitor" and all is well again.) If a
call for Data or Fax comes in, it will answer correctly, until the
next voice call comes in.
I'm waiting for someone to write a "fake" voice messaging app that
only resets the ring monitor when a voice call comes in. This way, you
can take advantage of SmartRing or the Operator without shelling out
big bucks for a voice mail app, or you can answer the voice calls
yourself, so the Fax and or Data servers can still operate.
* 5.9.3.1. How to obtain and install UNIMODEM V from Microsoft
Visit the Win95 OSR2 updates page to find and download UNIMODEM V
(Listed as the VoiceView update). To Install UNIMODEM V, use
Add/Remove Programs/Windows Setup and Have Disk... or find the
UNIMDM.INF file, right-click on it and hit "Install". Then you might
want to try re-detecting your modem, or choose from the additions to
the modem list to find your voice modem.
4.00.950B users will already have UNIMODEM V built in. NT Workstation
4.0 also includes it.
* 5.9.3.2. ...and I can dial out while they're all running too?
Absolutely. This multiple app functionality doesn't prevent you from
dialing out, because the apps are still listening to a TAPI port
rather than a COM port. Now do you think TAPI sucks?
* 5.9.4. Top ten TAPI server apps (Apps that answer the phone)
10. WinFax Pro 7.0 with Delrina's CommSuite
9. MS Fax (Comes with Win95)
8. UNIMODEM V's Operator Agent
7. Dial-up server which comes with MS Plus!
6. pcAnywhere32
5. ... (Uhh... any ideas?)
------------------------------
Subject: 5.10. OK that's all cool, but what about non-traditional modem-like devices?
* 5.10.1. ISDN Adapters
Dial-up Networking 1.2 and later comes with ISDN configuration
software, but the simplest ISDN adapters let you use any old version
of Dial-up Networking or other PPP software. Such examples include
Motorola's now-defunct BitSURFR and 3Com's Courier or Impact adapters.
Previous releases of this FAQ described how difficult it was to get
ISDN connectivity. Well, with the right adapter and a cooperative
phone company, it proves simpler than I thought.
NOTE: I used to refer to an ISDN "modem". Since there's no MOdulation
or DEModulation occuring in an ISDN connection (except when the
adapter provides analogue ports for regular phones and modems), the
word "modem" is not the right word.
* 5.10.2. Packet Radio transceivers
This came up thanks to the efforts of Gordon McAndrew
(gmca...@aec.env.gov.ab.ca), who originally posted about using PPP
over packet radio.
The solution was to use the null modem .INF file and issue
commands directly to the radio device in a dial-up script.
Unfortunately, Win95 insisted in sending a phone number string through
the connection. They worked around this by inserting the user name
into the space normally reserved for the phone number. Strange, huh?
I don't know the command set used for packet radio modems, but I'd
like to see a packet radio .inf file made up one day. For example,
enter the radio frequency in the phone number box. Replace all the
"AT" commands with appropriate ones for the radio. Thanks to Gordon
McAndrew's work, we already know that PPP and TAPI in general does
work over such a device.
* 5.10.3. Null-modem cables
I covered this already in Chapter 8, but I'll cover it here. There's a
MDMCBX.INF file, used to identify the device to Win95, that lets
you install a Direct Connection driver on a standard COM port. This
can work with stuff besides dial-up networking. To install it, use Add
New Hardware or the Modems control panel, and hit "Have disk..." so
you can point to this .inf file.
* 5.10.4. "Windows only" modems
TAPI lets you use any kind of telephony device, not just COM port
based modems, so it became fashionable to make "software" modems, or
non-standard PnP modems that don't occupy a standard COM port address.
To install this class of modem, hit "Have disk..." and feed it the
disk with the drivers for the modem.
If you can live without Win 3.1 or DOS support for these devices, they
will work just fine with Win95 apps. In many cases they do create a
DOS style device (like COM5: if you happen to already have four COM
ports) than you can access from DOS or OS-friendly Win 3.1 apps that
support non-standard devices. In other cases they will just show up as
a TAPI device without any DOS support. Be prepared to stick with Win95
apps (a good idea in any case) if you purchase such a modem.
* 5.10.5. PCI modems
PCI modems are brand new as of September 1998. The only reasoning I
can see for using a PCI slot modem is because you don't have any more
ISA slots on your system. PCI is really overkill for something 1/20th
the speed of a floppy disk drive.
What's worse is the performace these things give. A PCI modem from
Diamond, sold under the Supra label, has very poor latency compared to
traditional ISA modems or COM port modems; 500 ms ping times compared
to 120 ms or faster with a USR ISA modem.
* 5.10.6. USB modems
If you own 4.00.950B or later, or Win98, you can use modems that
connect to Universal Serial Bus ports. USB is like a high speed
version of Apple's Desktop Bus on the Macintosh, but is bidirectional;
you can send data to USB devices as well as receive input from them.
If you go USB, be prepared to abandon Win 3.1 and DOS communication
programs altogether.
------------------------------
Subject: 5.11. Oops... I have a Win 3.1 modem app too. How does that complicate things?
The original COMM.DRV still exists, and if a Win 3.1 app opens a COM
port through this device, TAPI won't try to open it. You won't have
any of the TAPI benefits with this app, and you'll have to manually
configure its dialing properties, manually close it so other TAPI apps
can use the modem, etc...
Non-standard COMM.DRV replacements usually won't interfere with TAPI,
because TAPI does not refer to this device at all. In fact, there are
separate VxDs and SERIALXX.DLL files (and the TAPI.DLLs of course) for
32-bit access to COM ports. The non-standard driver better not be
calling un-supported stuff in Win95 though.
In general, try to avoid Win 3.1 modem apps. As much as I lay the crap
on WinFax Pro 7.0, for example, it's a far better solution than WinFax
Pro 4.0 for Win 3.1. Hold out as long as practical for Win95 voice
mail apps too, so there's no argument between non-standard apps trying
to use the modem and conflicting with TAPI. Win95's supposed to make
using modems easier, and Win 3.1 modem apps don't help at all.
* 5.11.1. My Win 3.1 modem app claims to use TAPI. Will it work with
Win95?
I haven't seen a 16-bit TAPI app yet. Apparently they exist, because
one reader wrote about it.
There are references in the Win95 resource kit to 16-bit TAPI
programs, and the 16-bit TAPI.DLL and TELEPHON.INI files. I gather
that they will work as long as they use this interface to communicate
with the modem. Like Win95 TAPI apps, if this Win 3.1 app has an
auto-answer function, it should "nicely" give up the modem when you
try to use it for other connections, like Dial-up Networking. You also
don't need to specify the COM port where the modem lives; only its
name from the list of installed modems.
This one reader's app comes with a version of TAPI designed for Win
3.1, and it seems to interfere with Win95's Unimodem TAPI service.
Microsoft documented in KB articles Q120221 and Q150280, how
to edit or rebuild the TELEPHON.INI file, and how to enable the
Telephony control panel. In particular, the Telephony control panel
can remove 16-bit TAPI providers from your system, allowing 16-bit
TAPI apps to use the 32-bit Unimodem Service Provider.

Subject: 5.12. General TAPI Annoyances...
* 5.12.1. I just changed my modem, but the app won't work with the
new modem.
Not to worry. Win95 apps will look in an entry in SYSTEM.INI called
"TelephonINIChanged=" followed by a date. If the app notices that this
date is later than the last time you changed any TAPI settings, it
will ask you to re-confirm the new settings.
Each TAPI device has a unique port ID with it. If you remove and add a
modem, or you remove and re-add the same modem driver, this port ID
will change. Well written Win95 modem apps will check this and offer
to let you select (or re-select) your modem. One exception of course:
WinFax Pro 7.0 does not do this. After you change your modem, go to
WinFax's modem config screen and re-select your TAPI modem to allow it
to work again. MS Fax does this re-selection automatically, and picks
the first available TAPI device without your intervention. If you want
to use a different modem though, check the MS Fax modem settings and
select the modem you want to use.
* 5.12.2. Why do I get the "Please confirm blah blah..." requester
when I run a modem app?
Most likely because you changed your modem. Just make sure you select
(or re-select) the modem you want the app to use. The app will save
this new modem choice (and its TAPI port ID) and use it until the next
time you change it.
* 5.12.3. Win95 reports my modem as a "Standard modem." Where can I
get a proper driver for it?
In many cases, this is because the modem does not have a good
description of itself in its I registers (If you have access to a
terminal program, try typing "ATI1" to "ATI10" to see what responses
you get.) You can change the modem type during the Add Modem wizard by
hitting the "Change..." button and selecting your correct model. Win95
comes with a lot of modem .INF files that otherwise fit into the
"Standard modem" category.
If your modem isn't listed (like the newest voice modems), download
UNIMODEM V from MS's Web site, or check out the other modem .INF files
available at the same site. Also check the manufacturer's web site for
updates. You can probably still use the modem with the "Standard
modem" driver (if it's a Hayes (TM) compatible modem) in the meantime.
Or if you feel really adventurous, try editing one of the existing
.INF files to create a descriptor for your modem, and save it with a
unique name.
