They all pointed out that the DOS manual describes using

   MODE COM1:baud,parity,bits,stop-bits,P
and
   MODE LPT1=COM1

Unfortunately, it's not working.  The printer is set for 1200 baud,
even parity, and 2 stop-bits (not sure if it's 7 or 8 data bits).
So that's what I set the COM1 port to, then I issue the second MODE
command to redirect the printer, then I attempt to test it with

   ECHO hi > LPT1

Nothing.  The printer stays quiet, and the system locks up until I
hit CNTL-BREAK (that's if I added the P option; without it, after a
few seconds, the system complains about the port (or words to that
effect) and asks the ubiquitous question: Abort, Retry, Ignore?).

I did of course try several variations, particularly of the number
of data- and stop-bits.

One extra variable: to connect the printer to the PC, I had to borrow
a gender-mender from work. (The cable has two male plugs, as does the
PC's serial port.)  It's definitly NOT a null modem, as it's a ribbon
cable with connectors on either end; no place to cross the send/receive
lines.

Any more suggestions from you net.gurus and/or hackers? :-)

Thanks in advance.
