That's great :-P

With three small modifications it works - partially
Because not all of the devices were found, just one of them.

  $hUdp.EndOfLine = gb.Windows    ' has to be set

' $hUdp.Watch(gb.Read, True)     ' (does not work)

Write #$hUdp, "ST: ssdp:all\r\n\r\n"  ' a second CrLf


"gssdp-discover -i wlan0 --timeout=3" finds all devices. Especially the 
router (FritzBox).


But thanks for that.
