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

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.
