OnCOmm event does not trigger.

[Boomeral]

I have a basic program to test key click and reception of data on RS232 port. Computer1 is running this program and computer2 is running hyperterminal. When I send the data out from computer1, i can see the data on computer2; however, no onComm event triggers when data is received. KeyClick does not work either.
Does anyone know what needs to be modified?

Thanks in advance.
