QextSerialPort reading error: wrong values

[Lawand]

Shouldn't you be using unsigned char instead of char?

Thanks a million, this seems to have solved the problem, the only thing left is:

By the way, reading the first character in the buffer is not a good idea.

That is one of life's mysteries to me
I am really looking for a way not to do that, and I would really appreciate it if you told me how to...
