Yes. And hold something shorting pins 2&3 of the PC cable (transmit
looped back to receive) to verify that when you short them, anything
you type is now displayed, or is being displayed twice if it was
already being displayed once with the pins unshorted.
Also, if using hyperterminal make sure you set flow control to none.
This is very good idea I am trying it by today evening. thank you
