This should work.  Try taking out any TSRs in the machine:  the popular
DOSEDIT is notorious for clobbering CTTY.  So is CED.

DOS is also a bit more fussy about handshaking than many other programs.  So,
on the connector which plugs onto your COM1, tie together: DTR/DSR/CD, and
CTS/RTS.  (On a 25-pin connector, this would be 6/8/20 and 4/5.)
