BTS_Test_ASCI: Add UPLINK FREE / UPLINK BUSY test
A VGCS channel is activated. The BSC sends UPLINK FREE message and
UPLINK BUSY message. When the UPLINK FREE message is sent, the MS is
expected to receive several UPLINK FREE messages. Then the UPLINK BUSY
message is sent, the MS is expected to receive one UPLINK BUSY message.
