Simple serial port project?

Hi Greg!, the problem you are having could be due to the PC handshake
lines needing pulling up. Try this:
link pins 7 and 8, also link pins 4 and 6 (9 pin D type only)
" 4 and 5, " 6 and 20 (25 pin D type only)
Some PCs do not need this connection (they float to the right level)
other PCs will not play ball until these signals are taken care of.
