Command:
Response:
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.
