Cool! Thanks!

I compiled the rt_serial_uprog, but it can't open rtser0:

# ./rt_serial_uprog
rt_serial_uprog: timer started
rt_serial_uprog: can't open rtser0 (write)
rt_serial_uprog: stop timer

# lsmod

rtser[X] should be available as soon as xeno_16550A is loaded, right ?

Usually not - we have national holiday today, so I was doing my stuff as long
as I wanted :-)

Thanks and best regards,
Hannes.
