Hallo Dave!
Thanks for your respond.
I've done your suggestion. I connected two linux computers with a
nullmodem cable.
On the other computer nqc is working correctly, but it has installed an
older version of nqc 2.0.2 (on my notebook runs nqc 2.2., I hope, this
is no problem).
This is the output from my notebook (where nqc does not work correctly).
Here I started nqc fist on the notebook, then on the other computer:
spock:/var/log # nqc -v -raw 10
Tx: 55 ff 00 10 ef 10 ef
Rx: 78 0f 78 ff fc 00 00 00 f8 f8 78 00 c0 00 f8 f8 f8 78 0f 78 ff fc 00
00 00 f8 f8 78 00 c0 00 f8 f8 f8
Tx: 55 ff 00 10 ef 10 ef
Rx:
Problem talking to IR device

The other computer mostly did not receive anything from the notebook.
Sometimes on the first left rx field appeared a 72, nothing else.
I compared the setserial output for ttyS0 on both computers. Setserial
on the notebook pcmcia card recognized a UART 16950/954, setserial on
the other computer a 16550A. This was the only difference.
Regards.
Michael

| It looks like the serial port just isn't getting the right settings (baud, parity, etc). I'm not sure how to go about diagnosing/fixing it...NQC makes some rather straightforward POSIX calls to configure the serial port. If it is not working, then (...)
