Hi, there thanks for the reply.
I have tried it as explained, connecting PORTC.6 direct to DB9 pin 2. And still could not the the message.
I'm not sure if it is the MAX232 chip which is cousing the problem, MAX232 behavs as follows:

Wheb TX (RC6) from '877 is connected to pin 11(T1 IN), pin 14(T1 OUT) gives -10.2V, this pin is connected to pin2 of the DB9 connecter. (Am i sending a negative voltage level).

But pin 7(T2 OUT) gives 9.6V and this pin is left float.
This connection is supposed to work, it doesn't look like it at the moment.

Where can i find a working code just for testing purpose? A code which sends and receives data.

Cheers,
Tom.
