Serial response garbled #85

I have flashed the latest v2021.09-serial.hex file. The serial commands DO work! Which is great!

But I get a "garbled" response on serial commands.

Above screenshot was take just after a <T3000,255. command.

These are my settings: Are they wrong?

Also it would be nice if the baudrate, databits, stopbits, parity and flow control were mentioned in the documentation.

I just tested this with different USB to Serial converters, on different PC's. Same result.

115200 is indeed the correct speed. You could try reducing the speed in the code and your TTY to match in case there is some sort of interference? Have you tried the serial adapter with other devices?

I directly connected it to my Wemos and it disappeared... Very weird. I tried 3 different types of USB RS232 adapters and 2 PC's
