Good day.
I am using the commg.dll V2.83 and apparently I have a problem to establish comunicasion at speeds greater than 256000 baud.
I am using the Putty program with which I was able to communicate at speeds of 921600 and 2000000.
The IC also has communication to 115200 but this speed is not a problem.
I think it's possible that I'm missing something extra but I can not imagine what it is.
