oops, i did a mistake. even single trx support never supported poweroff.
the reason why it worked for me is that i send "SETTSC" and "SETBSIC"
commands to the transceiver. (calypso-bts requires "SETBSIC" because it
generates SCH itself). because one of these commands will fail, osmo-bts
ignores the response, so it does for "SETTSC".
i think it is not a clean solution to send both commands and ignore the
result. the "POWEROFF" should shutdown transmitter, stop receiving and
allow "SETTSC" (even with different value) again.
