I generally use an Intellicom 16K serial->Parallel
buffer/converter.  It works well at 38.4 with hardware
handshaking and has jumpers for almost any cable configuration
you need.

I use these for graphics printing of faxes on laser printers with
much better results than using the parallel port.  The Xenix
drivers for the parallel port go sort of nuts during graphics
printing, slowing the system down significantly (Intel 303 386-33
with 64K cache), and have been know to trash the VGA somehow
requiring a reboot.
