Allows the user to select the Rx Code Rate and Type
{n (x.x.x)}, n=0..7, x=0 or 1 (8PSK Only)
Allows the user to manually set the rotational ambiguity of the
uncoded* 8PSK constellation. This will force the rotation to one
of the eight possible states after demodulator lock.
*This is not a normal mode of operation for the modem.
{DISABLED, ENABLED}
Allows the user to disable or enable TPC Interleaver. Valid only
for Radyne turbo codes TPC.495 and TPC.793.
{ENABLED, DISABLE}
Allows the user to enable or disable the Differential Decoder.
Having the decoder enabled ensures proper phase lock. May not
be adjustable in some modes.

Allows the user to select the rate of in-band data for the ES to
ES, Async overhead channel. Only displayed when Effiecient
D&I with Esc Enhanced are selected.
