rtems-test with serial device and run.cfg

[Jan.Sommer at dlr.de]

Hello,

I have trouble figuring out how to run rtems-test with a custom command where the output is captured through a serial console.
In my ini-file I used 

bsp_tty_dev        = /dev/ttyUSB2
tester                   = %{_rtscripts}/run.cfg
bsp_run_cmd        = i386-run
target_off_command = i386-stop

We have a custom command which prepares the target device.
The device is connected to the development machine (running Linux) via a serial connection.
Now, the above did not work, since the run.cfg ignores the "bsp_tty_dev" setting and always assumes results via stdout.
When I change that, rtems-test tries to open the /dev/ttyUSB2 device, but fails to do so with:
error: opening tty dev: /dev/ttyUSB2: unknown

Which seems to be caused by this: 

Traceback (most recent call last):
  File "stty.py", line 77, in __init__
    self.fd = open(dev, 'rw')
ValueError: must have exactly one of create/read/write/append mode

I am not that familiar with the rtems-test internals. Do I need a different kind of configuration?
How do others use the "bsp_tty_dev" option (e.g. in the tftp tester)?

Best regards,

   Jan
