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 = reserved.
Bit 4 = reserved.
Bit 3 = reserved.
Bit 2 = reserved.
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 = reserved.
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 = TX Interface Module.
Bit 4 = reserved.
Bit 3 through Bit 0 = Binary representation (0 to 10) of
the number of interface transmit side stored faults.
Character 'h': Interface transmit side faults character 2.
Bit 6 = 1 always.
Bit 5 = Transmit Data/AIS.
