Sorry, 
didn't see the other replys before posting.

The Win functions does not care about zero etc....
Do a quick check with a scope on the TX line (I'll bet the '0' is 
sent ok), but then you have ruled the ARM out....
Then, do a TX of a '0' from the PC using loopback (and to be safe, 
measure that with a scope too......
