Hi again, i have another problem, i need to me able to send some serial data over a radio link at 9600 baud, and then feed this data into the parallel port on a PC. I have an RS232 transmit routine that works fine. But i cannot get any of the Receive routines that are in the Application notes AN510.AN555 etc to work properly if at all on on my 16c84. Any ideas. Cheers. -- +-------------------------------------------------------------------+ | Martin Bowman - University of Warwick, Coventry, UK | | - 3rd Year Electronic Engineering | | - E Mail (esukq@warwick.ac.uk) | | - Packet G7VHE@GB7COV.GBR.EU | +------------------ IF IT AINT BROKE - DONT FIX IT -----------------+
