It's more than just the init command. The z3801a also sends @@Ca, @@Cg, 
@@Ab, @@Ah, @@Aj, @@Ak, @@Al, @@An, @@Ar, @@Av, @@Ax, @@Ay, @@AB, @@AC, 
@@AD, @@Ba, @@Bc, @@Bk, @@Cg, @@At, and @@Bn, none of which are 
available on an M12 (which would be the logical target if you're going 
to the trouble of an adapter), so would need to be converted to other 
commands, and the correct response returned. In addition, the response 
to the @@Bb command (Visible sat status) would need modification.
