Guys, I was just messing around in Google, because the parallel port
in my hamshack machine seems to have given up the ghost. Windows says
it's OK, but it does not respond to a loopback test.

But, in my travels I came across these 4 web sites. The first one is
especially interesting in that it shows how you can use an USB port as
a serial port. Scroll down until you come to a section marked "Baking
and then take a look at the interface required. The others have very
interesting data on the parallel port, including the complete readout
of all 25 pins and what they do.

http://www.lvr.com/parport.htm   this one shows how to connect 2 PCs.

Just might be something in there for you guys running low on serial
ports, or wanting to use the parallel port in XP, ect.

And I'm sure one of our guys will grab that schematic and rip out most
of it to just make a keying line.
