Besides what Richard mentioned, be sure your baudrates are the same
on both ends. You didn't specifically set it here.

Also, I would not run untested programs on 2 ends at the same time. I
would test the oopic program, in isolation, using a terminal emulator
running on the PC, such as Hyperterminal, etc. Once the oopic program
is working ok, then try some fancier program on the PC [mobile?] end.
Otherwise, there is no way to tell which is working properly.

Also, I'd use something other than a 5 as the test value, since it's
not a displayable ASCII character.
