I don't think your modem is the problem. I think it's ProComm Plus
that's holding you up. I had a similar problem when I installed a Zoom
V.34I 28800 about 2 years ago (I have since installed a USR Sportster
33600 using the methods below without problems). There was no specific
modem file in the MODEMS.DAT file for it, so I thought "OK, I'll just
configure it within ProComm, and everything will work fine." Wrong!
The reason it didn't work right (and made the modem run like it was
in second gear) was because ProComm Plus (I use V2.01 DOS) uses the
modem file on start up and rewrites the values to NVRAM profile 0 each
time you start the program, and also writes the values to your setup
utility (Alt-S), each time you use the program.
The first thing you need to do is check the maximum port speed that
your version of ProComm supports. You can do this by looking in your
dial directory, pick any of the BBS's you have configured, and select
R(evise). When you get to baud, look at the maximum port speed. If it
says 38400, then you have the older version of PCINSTAL.EXE (05-01-91)
in your ProComm directory. No amount of file finessing outside the
program (such as the additional serial driver you're using) will help
the program go any faster. The older version of PCINSTAL.EXE was
intended to support a maximum of V.32 (9600 baud) modems. That's why
your new modem runs so slow. The program is not fully supporting the
features of your modem. You need the updated PCINSTAL.EXE (124854
06-24-92) and MODEMS.DAT (149626 08-22-96) to pump the serial support
to 115200. You can get these from the Data Storm BBS (314-875-0503).
If you already have the newer version (you can check by going to the
directory where ProComm is installed, typing DIR/P at the prompt, and
looking at the file dates), skip the next step.
The next thing you need to do is install the newer versions of
PCINSTAL.EXE and MODEMS.DAT over the old ones.
After you've done this, you'll need to make an entry in the MODEMS.DAT
file (it's an ASCII-based file written in ASPECT script language)
using your favorite text editor (such as EDIT provided with DOS) for
your Ellcon modem (it's not there, I've already looked). You want to
make sure you keep the indentation and line spacing the same as the
other modem listings, or you'll confuse the ASPECT reader used by
ProComm. Here's the entry I used for the Zoom V.34I 28800, also
Rockwell based. Check your modem manual for the specific settings you
want, substitute these settings in appropriately, and save the
MODEMS.DAT file:
Modem "Zoom V.34I 28800 V.34/V.FC/Fax"
   transmit "AT^M~~AT&F^M~~~"
   transmit "AT&C1&D2\A3&S1L0M0^M~~"
   transmit "ATS7=60S11=55S95=44^M~~"
   set baudrate 115200
   transmit "AT^M~~AT&W1^M~~"
   initstring="ATZ1~~^M"
   mnp=1
   no_connect 1="NO CARRIER"
   no_connect 2="BUSY"
   no_connect 3="NO DIALTONE"
   no_connect 4="NO ANSWER"
   baudrate=115200
If you wish to disable compression entirely, use %C0. I recommend
using %C2 to disable MNP compression, but allowing V.42bis because if
V.42bis encounters a compressed file, it will pass it through without
attempting to compress it further, slowing transmission. Otherwise, it
helps fully utilize your modem's compression ability, increasing
