In what way did it not work? Did anything happen at all when you sent
serial characters? Is the power supply OK?
You haven't given us much information to go on!
We don;t even know that the PC is sending anything. Have you tried a
'scope or breakout box or whatever to make sure the TxD line is doing
something when you try to send a character?
Also, 'Null Modem Cable' covers a multitude of sins. What ahve you done
with the flkw control lines?
