Is it possible to modify the monitor code when using a 'simulated serial' port for the monitor connection to allow it to break the code using the Stop button? I have the simulated serial port running on the external interrupt pins on port 2 of a 167CS? Both the embedded serial ports are required in the target application. I have used other monitors with simulated serial ports that could do this. Thanks Paul
I have used other monitors with simulated serial ports that could do this. How did they do it? I would bet that they didn't use just the RXD and TXD RS-232 lines. Jon
Its was in an old Hitex monitor, it could used the external interrupt pins on port 2 set at the maximum prtiority so that when an edge was received on the comms the processor could decide what it was to do with the message it received. I think it basically just sent a byte down the wire, this told the internals of the monitor to halt the program.

All you have to do is hook up a button. I know this is the STOP button in uVision2, but it will halt the program and uVision2 will sync-up. Jon
