This command causes all modem fault status to be
returned. To reduce the length of the response, fault status
is embedded into the bit structure of the characters that are
returned. Faults are indicated by a binary 1 in the
designated bit position.
Character 'a': Modulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Modulator module fault.
Bit 4 = RF output status, actual not programmed status
(1 = on, 0 = off).
Bit 3 through Bit 0 = Binary representation (0 to 10) of
the number of modulator stored faults.
Character 'b': Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer.
Bit 4 = reserved.
Bit 5 = Data Clock Synthesizer.
Bit 2 = I Channel.
Bit 1 = Q Channel.
Bit 0 = AGC Level.
Character 'c': Modulator fault status character 3.
Bit 6 = 1 always.
Bit 5 = Modem Reference PLL Lock.
Bit 4 = reserved.
Bit 3 = Configuration.
Bit 2 = Modem Reference Activity.
Bit 1 = reserved.
Bit 0 = reserved.
Character 'd': Demodulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Demod module fault.
Bit 4 = Carrier detect status (0 for decoder lock).
Bit 3 through Bit 0 = Binary representation (0 to 10) of
the number of demodulator stored faults.
Character 'e': Demodulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer Lock.
Bit 4 = reserved.
Bit 3 = I Channel.
Bit 2 = Q Channel.
Bit 1 = reserved.
Bit 0 = BER threshold.
Character 'f': Demodulator fault status character 3.
Bit 6 = 1 always.
Bit 5 = reserved.
Bit 4 = Configuration.
Bit 3 = reserved.
Bit 2 = reserved.
Bit 1 = reserved.
Bit 0 = reserved.
Character 'g': Interface transmit side faults character 1.
Bit 6 = 1 always.
Bit 5 = reserved.
Bit 4 = reserved.
Bit 3 through Bit 0 = Binary representation (0 to 10) of
the number of interface transmit side stored faults.
