I'm trying to hook my Apple //e and IBM AT together through the serial ports,
via null modem, but it only works in 1 direction.  Ideally, whatever you type
on one terminal appears on the other, but characters from the IBM don't get
through.

I have a Hayes-compatible modem that I can hook up to the Apple, which works,
but I don't get any characters back from the modem in response to AT commands.
It does work, however, because it dials out from an ATDT command, and once I'm
connected to a BBS, everything flows normally.  When the modem is connected to
the IBM, the AT commands are echoed normally.

I'm using some weird clone of the Apple Super Serial card, this one is id'd
only by 'SSB-1'.  Am I missing something in the null modem (I'm using a
breakout box to swap 2 & 3, ground 7 straight through) or should I just trash
this clone serial card and get the real thing?

Thanks for any help.  If I can get this working, I'll soon have most of
comp.binaries.apple on my (IBM) bulletin board.
