Yes, it';s not difficult to
bit-bang the handshake protocol. However, I
understnad that most modenr PCs don't have parallel ports any more, and
the USB-Cntroings pritner cables can't be used for this AFAIK. Yes, you
can make a USB-'user paralel port' interface and use that to talk to a
GPIB, but that;'s as much work as makign a specific interface.
