MON166: Using the Simulated Serial Port

Information in this article applies to:

• C166 Version 3.12 and later

QUESTION

Are there any caveats to using the simulated serial port of the MON166 Target Monitor?

ANSWER

There are only a few negative points to using the simulated serial port.

1. There is no interrupt associated with the simulated serial port, so, you can't use the stop button in the debugger to stop program execution and start back where you left off.
2. This means that you'll have to set break points and single step through your program (but that's not a major limitation).
3. Since the bootloader only works with ASC0, you'll have to burn an EPROM that contains the simulated serial port MONITOR.
4. You'll lose 2 I/O pins with the simulated serial I/O.
