QNX 4.25 on ELAN400

I’m having trouble with the internal serial port on ELAN400 with QNX 4.25.
When I start Dev.ser it seems fine, it reports the correct irq and i/o, but I
can’t send or receive anything.

Does anybody have any idea what to do?

Thanks

Hi

How are you sending and receiving data? If you just cat in from the
serial port when something like a mouse is attached and you move the mouse,
do you get any data? Do you know if the serial port works correctly?

Here’s a suggestion. I use hd instead of cat.

You should look at the output from a working system first. It will give you
a very good idea of when your real problem is mismatched baud rates.

stty < /dev/whatever

is also very helpful. Look for anything that is paged.
