Kind of makes me want to rush out to the shop and buy one... just
for the challenge.
I know that a "Rubiks Cube" is probably cheaper, but it's not quite
the same challenge as trying to beat a computer into submission.

Alternatively search for WinPack or WinTNC, the windows versions.

got it to work by now!
I've tried various drivers under real dos, linux and windows and nothing
communicates with the modem.
I'm starting to think they were so cheap because they're defective or
something?

Think you need more than drivers. The baycom modem is a pretty dumb thing.
The Packet generation is done in software by the baycom program. Think the
hardware just produces tones of the right freq and converts async to sync.
Even the squelch is done in software.
So you need specific software program to drive it. If you are lucky Baycom
program will do it. However, It may be a propriatory program in which case
you are stuffed unless you can find someone who has it and can copy it for
you (which they may be reluctant to do if it was originally for commercial
use)
With most packet TNC's you just need a terminal software such as winterm as
all the paket stuff is done in the TNC, you just use the PC to alter
settings and get your mail off it. The Cheap (wrongly called) TNC's such as
the Baycom, need the PC to do all the stuff a Normal TNC would do itself -
packet frame gneration and decode, mailbox etc.
Take it apart and post what the chip(s) have on them ?
Baycom uses the Texas Instruments TCM3105 modem Chip. It may be that the kit
you have there is ex-commercial packet radio terminal, in which case it
make's your hunt a little more complicated.
Edd
as the case. There are 3 IC's in there. I think 1 is a Motorola with the
code MC74HCO4AN FAR9422 The other 2 chips may be Texas but I am not sure.
The codes are 57D7Y6T TCM3105N and 58A38TT MAX232N. The board is printed
Patronix 6/10/95.
I hope this sheds some light on this problem.

frequency-shift-keying (FSK) voice-band modem that uses silicon-gate CMOS
technology to implement a switched-capacitor architecture. It is pin
selectable (TXR1, TXR2, and TRS) for a wide range of transmit/receive baud
rates and is compatible with the applicable BELL 202 or CCITT V23 standards.
The Max232 is an RS232 level converter. All pretty standard stuff really.

software to use thats all. Seems to me its only been tried with a CB, nobody
mentions Amateur kit. After all the packet network is far more established
on there, so my first test would be there.

to COM 1. I think it must be a cable wiring problem!!!!

No difference between CB and amateur kit in this regard. (If you try it on
CB you are probably breaking the law but that's a side issue). Mic and
speaker connections, PTT etc more or less the same.

I'd recommend WinPak though as software. Setting up the baycom stuff seems
to be beyond a lot of people. WinPak worked with my Baycom OK last time I
tried it. Baycom lead was pre-wired for my FT736 but didn't look that
complicated.
download winpack from here:

> to be beyond a lot of people. WinPak worked with my Baycom OK last time
hang on I just checked. The latest version of WinPAK doesn't seem to work
with Baycoms (works with regular TNC's)
Must have been some other software I was thinink about.
You'll have to struggle with Baycom DOS software for time being.
Simon Bussey
As I've already said i've used the Baycom software! Under DOS, with a packet
engine under 98 and with linux and *nothing* works with this modem. I've
used baypac modems fine before which are based on baycoms. So please no one
else say have you used the right software unless *THEY HAVE USED THE
SOFTWARE WITH OUR MODEM AND GOT IT TO WORK*.
So the point remains NO ONE HAS GOT ONE OF THESE MODEMS TO WORK!!!!

Have you tried posting details of your problem on the
alt.ham-radio.packet newsgroup? They're quite a helpful bunch on
there.

here http://www.peaksys.co.uk/. I used to use my original Badger Boards
Baycom modem (still have it somewhere) with this software under windows 98
too. You have to download a baycom driver to use in conjunction with bpq to
get it all working, but that is fairly simple from what I recall (been a few
years since used packet). There is also mention of a mod to the modems that
needed to be done because of problems with 16550 buffered UARTS on RS232
ports, maybe this is what is needed to get these working as both use the
74HC04 hex inverter. Just a thought.

see www.tigertronics.com for all the s/ware usable with baycom and DOS or
WIN 3.1/98 and 98 listed
once you have it running with the baycom modem
RTFM at the baycom site.......
its even in english.
If you have done this then its a cable problem i think its just 3/4 wires
connected in my old one.....
mabe they have too many connections or the wrong ones connected.
again see the manual
hope this helps....
I will be getting an old lap-top this w/e and will have a go next week and
post results .....
Hope you get it working befor then Packets fun .....Honest well it could be
if us lot get on it Ha Ha.

serial cable and not a 'modem' serial cable. I believe the modem ones are
crossed wired. Anyway the 'normal' cable makes the modem do something when
you turn it on, also using the baycom software and trying to probe the modem
the lights flash! buts thats all. I still can't get it to work but I can now
make the lights flash! lol

What have you set your port speed to, in whatever software you are
using? Try 1200.
Nick.
TonyWard
make sure the port/comm number in the scc. ini is set to comm port you are
using i.e comm 1 on the computer is 3F8 irq for that is 4 i think
with the baycom software the cursor in the top left should be flashing at
about 1 a second (software working)
know press enter with squelch up and it should transmit a CQ
your nearly there I think.

You need a Null Modem cable to hook a baycom up. You can find info on
connections at this site
http://www.loop-back.com/null-mod.html
Christopher Steen
but still haven't been able to TX anything.
Could someone give any advice on the modem (Commtel PM1200)?
Cheers.

you could go to this page and click on the

check the cable connections as in the above post you may have too many wires
connected.

then used an shi*ty computer which has been sitting in my loft for 5 years,
note that Win
95 98 etc makes complications when a dos program tries to use the com port,
something to do with shared I/O or something, so I used a Dos only system
(386), with Win 3.1.
Had the baycom 1.6 software on disk, went in to install.exe, setup the coms
etc. loaded l2.exe, loaded scc.exe, typed ":be 10" pressed enter, and there
you go, the cb tx'd and you have one 1200baud packet station. .command
":BE" is short for beacon by the way so it should tx and send out a short
message. Hope this helps you all, only I'm not sure if it 100% works as I
have nobody to test it on and it does make a different sound to other packet
modems I've heard. Anyone in the Watford area with a packet please contact
me, cheers.
