hi all,
iam currently programming MC68360 board processor SCC's to work for Synchronous HDLC and iam taking out RS232 pin outs from the P2 connector.
I have initialized the registers and set jumpers according to the instructions. but iam not getting the Clock signals from the TXCLK lines. can u pls give me some hints what r the things that can go wrong which will lead to this kind of problem.
Are you seeing flags on your TX line ? 0x7F at whatever bitrate you are using. If the transmitter is enabled, HDLC mode selected you should see 0x7F on the TX line. If not, then either you have not enable HDLC mode, or TX is disabled ot you have selected to not have flags in idle mode.
Regards Anton Erasmus
Flags are 01111110, i.e. 0x7e.
