Do you ever get it to communicate?  If not then your parameters
(baud rate, handshaking) may be wrong and mismatched to the remote

Can you get the remote to communicate with a terminal program?

One useful trick is to find a laptop computer and see if you can
communicate between that and VEE as a debugging step.
