Yes, I tried this first with the old version, and that one didn;t
complain. The 4.1 Btea 3 version complains that this speed is non
standard, so I tried it at lower speeds, but it gave me the same result.

I double and tripple checked that. There is nothing on the device. The
old device names don't even exist on the system, so that can't be it
either. And there are hardly any processes running at all on this machine:

That's a bit of a problem since that would require another cable (9pin
instead of 25pin). And I think I have found the problem, I just don't
know how to solve it. The process that is put in the background in
the onDev function exits before any output is generated by the serial
port. Probably even before any data is sent to the serial port.
