Hi, Yes, nothing appears. When I interupt the process (ctrl-c), an error appears: --- close failed in file object destructor: sys.excepthook is missing lost sys.stderr --- Jannik 2015-02-26 15:56 GMT+01:00 Ben Coman <btc@openinworld.com>:

Hi Jannik,
One other thing I just thought of: Check and see if your rostopic program is actually writing to standard output, as opposed to writing directly to /dev/tty. From a terminal window, I think you could do this:
$ rostopic > out.txt
Would using a pipe better represent the interaction with OSProcess? e.g... $ rostopic | tail
cheers -ben
