[Coco] Plugging more stuff in to the RS-232 Pak

[Dave Philipsen]

I would say it's within the realm of possibility.  I suppose you could 
somehow wire an LED to a handshake line and do it.  I once wrote some 
code to do exactly what you talking about.  It wasn't on a CoCo but I 
bit-banged an output bit on a 68HC11-based device to create the signal 
for an IR LED which controlled a NTSC video printer.
