        Thanks! I've got the book right here in front of me. While it covers the
various modes of parallel port handshaking, However, it does not give the
BIOS calls to access the ports. I'm trying to avoid "bit twiddling" in my
code. For SPP output, I can just to a call of INT 0x17, function 0x00 and
it does the whole SPP handshake. I'm now looking for a similar BIOS call
for a byte mode read. Page 204 of the book says "Another IEEE committee
is developing a standard BIOS, or API, for using the new modes." Anyone
know what they are?
