Laplink Cable Pinout ?
romolo albuquerque
Hi. Does anyone out there know the pinout of a Laplink cable. A cable
used to connect 2 pc's through the parallel port to transfer files using
interlink and interserv that come with dos 6.x ?
This is a cable with 25pin male connectors on both sides..
Any help is greatly appreciated.
thanks..

I *think* it's straight through, pin 1 to pin 1, etc...

We pinned one out and came up with:
1-1
2-15
3-13
4-12
5-10
6-11
14-14
25-25
All others are not neccessary. We made a cable and have been using it
with no problems.

Note that this cable has to be symmetrical, so you also need
15-2
13-3
12-4
10-5
11-6
Four of the data leads on each end go the four status lines on the
other end, which are used for input. A bi-directional parallel port
is *not* required for this to work.
If you have DOS_6, doing "help interlnk" and looking under "notes"
will give you pinouts of both the parallel and dual-headed serial
cables.

Oops, you are right! I forgot to put those down. Thanks for the
correction.

Hello,
Now that I have programmed modem for data communication and faxing, I
am starting on programming a voice modem. I am doing it on a BOCA 14.4
voice/fax/modem. I have already collected a list of rockwell chipset AT
voice commands.
It seems I have no problem initializing a modem, dial out, and when
connected, play a voice file over the phone line. I can also detect and
record the DTMF tones when I press the buttons on the remote telephone.
However I fail to record any conversation. I do not know what is the
problem. I did the following: ("-->" means AT commands sent to modem, and
"<--" means modem response.)
--> AT&F&C1&D2M2L3
<-- OK
--> AT#CLS=8
<-- OK
--> AT#VLS=0
<-- OK
--> ATDT 123-4567
(It dials another phone line I have in my room. The phone rings
and I pick it up. After a few seconds modem respond with VCON)
<-- VCON
(I press buttons on the telephone: 1, 2, 3)
<-- <DLE>1<DLE>2<DLE>3
(So it detects DTMF tones on remote phone as expected)
--> AT#VBS=2
(set 2 bits per sample. I initialized UART at 19200 bps so it
should be OK with 2 bits per sample. The sampling rate is 7200Hz)
<-- OK
--> AT#VRX
(Now let's start recording conversation from remote phone)
<-- CONNECT
<-- (A dozen or so garbage characters comes back, but then nothing)
(I keep talking loudly into the phone, but nothing comes out from
the modem.)
(But if I press the buttons on my telephone, instead of the usual
<DLE>1, <DLE>2 thing, I get a couple hundred garbage characters
from the modem. So it sees it will record the button pressing as
sounds but will not record my conversation through the handset!)
--> q
(I pressed 'q' on the computer keyboard so it stops to record.)
<-- VCON
(I press 1, 2, 3 on the phone)
<-- <DLE>1<DLE>2<DLE>3
--> ATH0
(Hang up modem. test done.)
So what did I do wrong that after I issue the "AT#VRX" command it will
not record my conversation? I tested the modem using the bundled voice modem
software so I am sure the modem is in perfect working condition.
Any help will be appreciated!
