I just redid a TSX system to accept a modem, and it worked OK
(after getting help from a lot of people via net.decus).

I was using a Hayes Smartmodem 1200 connected to a DLV-11J.
I tried using the $PHONE flag and this DOES NOT work for this
configuration.  The reason is that the $PHONE flag makes TSX look for
the modem status signals which indicate that it is properly receiving
a carrier from the remote modem.  If not, it 
logs you out again.  
A DLV-11J only has connector pins for data in, data out, and ground,
so there is no way to tell it that the modem has answered the
phone.  
The only LSI-11 interface card thgat supports these
signals is, I believe, the DLV-11E, which is a single-line
serial card (the J is a four-line, non-multiplexed).

Anyway, I set the LINDEF up exactly like the other 4
lines, and also changed the macro that defines the
total number of lines.
One problem that cropped up later is that
the other lines had been set for 100-character I/O buffers
on the serial lines.  This is too small for KERMIT file transfer
(to the 11 from a PC), so we will bump iit up to 110.

Thre other thing I had to do was tell the Smartmodem not
to send result codes or echo commands, else the
characters sent (e.g. "RING" bounce back and
forth forever).

Good luck.  I hope that my recent expereince gives you
hope. I am sure that others on the net will also be glad to help you.
