Does the baud rate match on both ends of the connection?
That's the transfer speed and if it doesn't match you'll just see garbage on the receiving end
(if anything at all)
Also, the fact that the led comes on only indicates data at the source, and nothing about it's format.
I would suggest using putty (available on line free) on the receiving end. that way you can play with the baud rate parity, etc
without changing the software (until after you know what you're dealing with). In addition, since you indicate that only the data
lines are being used, I expect something like full duplex may be used for hand shaking, which may or may not be the case.
