Subject: Loosing chars with ZyXEL 1496E+ and Coherent 4.0.1

Hi there!

This is a modem (ZyXEL 1496E+) / Coherent (4.0.1) problem.

I'm running Coherent 4.0.1 on a i386SX/16 with 2 MB and a ZxXEL 1496E+
having real trouble connecting them. I have never faced these problems
with my old Hyundai 2400 bps internal modem. The ZyXEL 1496E+ is
connected to a multi I/O card with 16450 UARTs, so I thought, I'd better
run at no more than 19200 bps. I use device "/dev/com1fr" for the modem.

Characters get lost between the PC and the modem. "at&t8" shows clearly,
that characters get lost, so using another UUCP suite like Taylor won't
help (much). I guess there's some trouble with my device driver.   :-(

Just to make sure that those people who may be able and willing to help
me have all the information they need, I supply "everything".      :-)

My feed "incom" has a Worldblazer Modem and both modems seem to agree
to use V.32bis for the connection, but there are many errors.
Using the very same modem at V.22bis (2400 bps), everything works fine.

What can I do?
