Description of Arguments
Command or Query.
Defines AUPC operating parameters. Has the form abc.cd, where:
a=Defines action on max. power condition.
(0=do nothing, 1=generate Tx alarm)
b=Defines action on remote demod unlock.
(0=go to nominal power, 1=go to max power)
c.c=target Eb/No value, for remote demod, from 0.0 to 14.9 dB,
where numbers above 9.9 use hex representation for the 1 st
