" I know folks have had different success with various baud rates, for some higher rates seem to work OK but not for others and I wonder if this 'weak tea' drive on the three serial output lines is part of the issue."
Maybe. But my testing never showed problems at the higher baud rates between T102/M100. Though I tend to test more with a 102, so given what you're saying maybe that's why I didn't see an issue. Where I saw issues at high baud rates it was more an issue of whether the baud was supported by the peer (most PC UARTs/USB-Serial devices support 38400bps, but some don't support 76800bps, at least at driver level). -- John.
