In tx mode, these bits determine what compression methods
0 0 MMR, MR, MH, EFC are available. The methods are listed in order of priority; if the
1 0 1 MR, MH, EFC other end cannot receive using the highest priority mode (for

MR, MH
example, MMR), the machine will step down (for example, to
1 1
MH
MR). EFC is not used with MMR, or when communicating with
another maker’s machine.
In rx mode, these bits inform the transmitting terminal of the
type(s) of coding that the machine is able to receive.
