Digi(Central Data) EL16 terminal server woes




Hi.

I've scanned the arhives for similar problems to this, and as fas as I can
tell the jury is still out on using ethernet terminal servers with class
2 modems.

If I use a Multi-Tech MT1932ZDXK on a hardwired serial port everything
works fine - faxes send with no problem whatsoever.

However, if I try and set the same modem up on the EL16 server - drivers
for which make a device file which appears just like any other modem
device - I start having problems. Sometimes batches of faxes send no
problem, but then I start getting "Unknown problem (check modem power)"
errors, and only one in six tries will succeed.

We run IRIX (6.5.6f), so I've tried using the ttym* and ttyf* devices (no
different).

Does anyone have any suggestions which might improve matters? I'm sure it
must be possible to use ethernet servers for this kind of thing. How else
do ISPs like Demon Internet provide the mass fax->mail gateways which
require *huge* amounts of modems?

I've included a sample log file ...
