COM port &modem problems
MikPat2000
Need some help. Am about to start using the hammer to fix this problem.
Here is a brief history of the problem. Any input would be nuch apreciated.
Since I've had DSL, haven't had much use for modem. Tried to use it
recently to fax something I scanned in and am having trouble. Decided to
remove modem from system and unistall all communications software that came
with modem and rfeinstall everyhting. When I reinstall, WIN98 auto installs
the modem to port COM3, but when i check my ports in the system part of
control panel the modem shows that it is on port 3, no problem you say,
except when I check my ports I do not have COM3 port.
Have tried installing software firs and then trying to add modem, in this
instance it lets me select which port to install it to. I have tried
selecting each of the ports that my system says I have ( COM1, COM2, and
COM4 ). 1& 2 dont work, but that's because I know they are designated as the
serial ports on the back of the tower. When I put it on COM4 all seems fine
until I try to use the modem and it says that it could not open port.
Don't rally know waht to do and am hoping that someone in this group can
point out some simple little thing I am overlooking.
Don't know how much info you need so I'll give all details that I know.
Thanks

I didn't have the disk with the modem drivers and windows didn't detect the
correct modem. Although some modem drivers 'worked' at least in the sense
that windows didn't report them to be not functional, the port settings
didn't match or work no matter what I tried. My soultion was finding the
exact drivers for my modem. Maybe it's a driver problem? Also network card
and modems require certain network protocols. If you're sure about your
drivers, go into your network settings and make sure you have the Dial-Up
Adapter and the TCP/IP protocol. You also will probably need either the
client Microsoft Family Logon or Client For Microsoft Networks. Hope this
helps...

going into control panel>>modems>>diagnostics and then selecting your
modem port and clicking on more info, which should get the computer to
try and communicate with the modem when it was on com3? If it is
successful then no problem, your modem should work no matter what your
'system properties' say about com3.

Some modems use their own uart, which i think yours does by the sound of it,
so it can't use a port that physically exists on your pc, com3 should work.
I've had the same problem and i suspect with the same modem, but this is
usually due to it being a software modem that can't be handled by the pc, as in the
case of a 486 !!
I suggest you boot in safe mode, remove all the entries referring to com ports
and modems in device manager, reboot and let windows re-install the ports.
Don't manually add any.
Then install the software using the install.exe or setup.exe on the driver cd,
allowing windows to do it doesn't work so click cancel if windows hardware
installer asks for modem drivers.
When it asks for the port to use, choose com3.
If you have any devices in device manager under a yellow 'other devices' delete this entry
and then reboot, hopefully then it should work, if not a new modem may be in order !

which are known as virtual ports.
it is COM3/COM4.
If Windows is fixing it in COM3/COM4,
that is the correct one.
COM1/COM2 are Physical Serial ports
which are for External devices NOT for
internal modems.

recogninising the COM3/4 ports
You can reset them up by the following
this procedure.
The following procedure is recommended by
the Editor of a well known computer mag to setup the Internal Modems.
The Internal Modems need to be setup to operate on either COM3 or COM4, =
which are
virtual ports. Windows needs to setup to use
either of them.
1. Go to Control Panel and Double click on "Add new Hardware" and then =
"Next" button
twice. Windows will search new hardware. When it finishes, even if =
it has found your modem, click the option that says "NO that the device =
is not in the list" and click Next. You will then be asked if you want =
Windows to search for the device. At this point you should choose
the option to select your hardware from a list.
2. In the "Hardware types" list hightlight "Port com+lpt" and click =
Next.
In the next window hightlight "Standard Port Type" in the left =
pane/window=20
and "Communications Ports" in the right pane/window click next and a =
new window will=20
present a summary of the ports just installed. Click Next Windows will =
add the ports and ask you to restart. Once Windows started it may detect =
your Modem and Install it. If it does not then>>>3
3. Go to Control Panel and Double Click "Modems" and choose "Add New =
Modem"
and tick "Do not detect my Modem....".
Now you will see a list. If you know your Modem select it from the =
left window. If not, select the "Standard Modem Types" under =
Manufacturers and under the Models=20
Standard 56k v90 Modem"=20
Click Have Disk and put the drivers disk in
the Drive(A or D) and Windows will install the
correct driver.

Not entirely. My understanding:
Basic IBM PC architecture allows for two, and two only, UART
chips (UART = Universal Asynchronous Receiver-Transmitter =
serial port) normally known as COM1 and COM2.
Each of the two physical serial "ports" - i.e. sockets - at the
back of the PC is connected to one of those two UARTs.
You can configure any number of virtual serial ports - with
numbers ranging from 3 upwards; these are for use only by
internal cards, and in fact map to (make use of) the COM1 and
COM2 UARTS. All odd numbered virtual ports map to COM1 and all
even-numbered to COM2; you can only use one even numbered port
and one odd numbered port in any given hardware configuration.
If you have more than two serial devices configured within the
same hardware configuration you risk conflict aggro unless you
can be quite sure that two potentially conflicting devices would
never in fact be used at the same time.
You're correct in suggesting that only external serial devices
that actually plug into the COM1 and COM2 sockets (e.g. an
external modem) should be set to use COM1 and COM2; all internal
serial devices (such as internal modem cards) should use COM3 or
4 (or higher).

I don't think this is strictly true, some modems which don't have an on board uart
do use the the ones on the motherboard, in some cases where the modem card can only use
com1 or com2 this involves dissabling the onboard port to allow the modem to use its own
Both the above generally only apply to old modem cards though, thesedays they all tend to have
there own uart which usually can be set to use various addresses and irq's.

first and some have two sets of drivers and the second set will not work without the first
mine has an Enumerator which has to be in first as this is the platform for the modem drivers.
I guess some need special registry entries or files which don't get put in if you just do it from the inf file.
