Faxaddmodem seems to configures them almost right, I had to modify the dial command slightly. but every time I send a fax, it aborts at the very end, despite the fact that the pages went through  just fine and were confirmed by the recieving end. Here's the tail end of the transcript showing the error:

I was having exactly the same problem, with the same type of modem. 
Except I am using Unixware 7.0.1 on a PC.  The problem seemed to be that
I was using the modem on an Equinox SST port.  When I moved the modem to
a COM port, the problem went away.  Every fax ended in a FHNG:2 even
though it was received on the far end okay.  I suspect it was caused by
a flow control and/or an RS232 signal problem on the Equinox port.  I
have not had a chance to look any deeper for the cause.  I am going to
be trying a USR Courier V.Everything modem on the Equinox card to see if
it has the same problem.
