FYI: for non-standard baud rates;
I use Linux for all development work and?a USB-2-TTL serial converter for serial I/O. I tested with with CH340 to see how much baud-rate error would be tolerated at 57.6Kb and found up to +7% error was still functional but +10% was no-joy. I also found that anything more than -2% was no-joy.
I use PICOCOM for terminal emulation, which allows one to use ANY baud rate you tell it, so if you are using a 2 MHz oscillator, simply tell PICOCOM your ACTUAL baud rate is 62.5Kb (or whatever) and it'll work. Not sure about WINDOWS terminal emulators. Try it and see.
Thanks Scott,
The terminal programs I normally use (ProComm and TeraTerm) don't support odd baud rates; I'll have to try the one you suggested. It sounds like a good tool for testing baud rate accuracy.
I did find a source for more 1.8 MHz resonators. I ordered directly from Tayda Electronics in Thailand, and they arrived. :-)
Best wishes,
