Hi,
thank you all for you help.

I thought about that, but I could not find 'net' command.
Can this be done from the Python script without calling halcmd?
I just tried this and it worked very well:
h=hal.component("mycomp")
h.newpin("com-pos", hal.HAL_FLOAT, hal.HAL_IN)
h.ready()
msg=Popen('halcmd net emcmot.03.pos-cmd mycomp.com-pos', shell=True,
stdout=PIPE).stdout.read()
h['com-pos'] = newpos
It's fast and feels responsive. Nice. Real time is not a requirement.
However I have the feeling that that's not the nicest solution. I guess
I should use the 'loadusr' hal coammnd in my .hal file to load the scrip
and use the '-Wn mycom' parameter to wait for the creation of my
component and than create the link between the signal and my pin in the
.hal file.
See you
Florian
