Looking for an explanation,
File Source -> GMSK MOD -> GMSK Demod -> Head Block -> File sinks
Works fine, terminates after x number of bytes have been transferred and
File Source -> Packet Encoder -> GMSK MOD -> GMSK Demod -> Packet
-> File sinks
Does not return after head block limit (just hangs). Seams like the
encode/decode block is not exiting?
