We have a number of Multi-Tech and Telebit T3000 modems connected to
Ultra-2s running 4.0pl2 under Solaris 2.6.  Though our Multi-Techs
work fine, the Telebit modems run into reproducible problems sending
to certain fax machines.

We often get into a situation where the cover page is retransmitted
3 times within the same call, then the call is terminated.  Our
clients see over a dozen cover pages with no content sitting on their
fax machines, and needless to say, they're not pleased.

Here's a comm log of such a transfer:

I suspect the 'SEND recv RTN' is a clue.  I've tried adding
'Class2DDISCmd: AT+FDIS' to the config file for these modems to
no avail.  Any ideas?
