sorry i should have said,
I am using two telegesis wireless modules, one connected to my sensor circuit via MAX232 and PIC16F74, and the other connected to the PC where the telegesis terminal software is running. I am sending out the at+bcast:00,"data" from the sensor circuit, which broadcasts the message to the network. This part works since the pc end is recieving the data but for a limited time i.e. the sensor circuit is sending out too much for the node to handle. When the sending node completes the transmit it confirms by sending "OK" which is what i am trying to read with the PIC. So that the PIC is synchronised with the wireless node.
Hope this clears up what i am trying to do
Thanks again guys
