Disable or enable the IFEC Interleaver.
Enable or disable the Differential Encoder. Having
the encoder enabled ensures proper phase lock.
May not be adjustable in some modes.
Select the scrambler type.
Enable or disable scrambler operation.
Select the framing type.
ED&I Only
Available when enhanced async is enabled, sets
the Earth Station to Earth station in-band rate. In
most cases, this should be set to the same rate or
higher than the ES port baud rate. When this rate is
set lower than the ES port baud rate, make sure
that the actual transmission rate does not exceed
the in-band rate, otherwise, characters will be
dropped.
