Hmm. Multiple documents? Are all parts of your fax in the same
resolution (which might help, if there is some screwballness going
on there)?

I also seem to remember a problem with RTS/CTS under some IRIX operating
systems. Have you tried software flow control?

Whoops! You might also try using Class 1: a lot of modems seem to have
problems in Class 2 or 2.0, and I haven't seen any simple fix posted.
Also, why is it barfing on this command?

You might run probemodem to check on this, and look in the manuals.

Umm. Flow control barfage?

And it's finally dead.....

Try Class 1 and see what happens?
