Hi Jef. Hi all.

Jef, a possible workaround/solution.

Assuming the Pentium is running Win 9x I believe I have a piece of
freeware/public domain software to run on this machine which can *redirect*
from e.g. com3 to com2.

It allows a Palm OS Handheld to make a serial connection to Windows box and
use this machine's modem as an external device.

Your problem _sounds_ similar so let me know and I'm sure I can dig this
software out.

The following _feels_ right but due to my current mental state (see below) I
may have dreamt it ...

Using Windows' Hyperterminal

Linux box connects to Windows box via serial line.
The Windows box has a TCP/IP stack which is bound to com<where serial cable
plugged in>
Windows box has another TCP/IP stack bound to com<where modem is logically

Windows Network settings would include something resembling this:
    Dial-Up Adapter
    Dial-Up Adapter #2
    TCP/IP -> Dial-Up Adapter
    TCP/IP -> Dial-Up Adapter #2

I'm afraid this is vague due to my working night-shifts with accompanying
sleep deprivation; a one-way ticket to temporary psychosis.

If you're looking for a solution which does not utilise Windows I shall have
to rethink. However, using Gates' OS as nothing more than a glorified set
of modem drivers has a peverse appeal.

Regards to all.
