I use two tools. One is called SIO and was given to me by the author
and another I got off the net was lptcom1

sio is like the progam someone else described in that it sends a file
of postscript with handshaking and displays messages.

the other is lptcom1 which takes lpt port data and redirects it to the
com1 port with xon/xoff handshaking. It seems quite reliable.

The problem with receiving messages back from the printer is what do
you do with them? For example if you make the driver blort the message
on the screen then it gets almost impossible to see what mode the screen
is in. If it is in graphics mode and not text mode then you might
not get what you want.
