tei and oml ts assignment

hello how do i set the tei and timeslot for a bs11? of course i know bs11_config and the tei_oml parameter, but it don't seem to work. i tried ./bs11_config tei_oml 4 30 and 30 4 (to set the timeslot to 4 and tei to 30). but when i query the bs11, it still says timeslot=1 and tei=25. I tried it with and without disconnection of the bs11. how do i call bs11_config correct for that purpose? T. -- Wer Rechtschreibfehler findet, darf sie behalten!
