I think not. I think it adds extra facilities to BASIC -- either as an
extra 'device' that you can OPEN a stream to, or as a set of routins to
CALL. I don;t know which.

I can't help with the Windows end, but the 8 pin DIN connector on the back
of the HX20 is a RS232 port with a fairly sane pinout (I can look it up
if it's not in any of the manuals you have). That could be linked (with a
suitably-wired null modem cable) to the serial port on a PC.
