While not completely the same, I have had numerous problems with the
Microcom modems as well, including a situation where the modem goes
off-hook and stays that way *FOREVER* until I manually pull the modem
out of the slot to reset it. This happens an average of 1 modem per
day...

I too have gone through all of the same steps, Microcom blaming it on
Livingston, upgrading the software in both the modems & the portmasters, etc.

I would be interested in this... We're using standard telco octopus cables
that we had to modify to be to specs.

I would have to agree at this point as well..

That would be great!

This is already in there... That's what the modem table is used for.

Yeah! And when the hell are you going to get V.34+??? ;)
