Note: Command <2626h> is only valid if an asynchronous interface card is installed. If
not, this command is ignored. Note: The following command will also turn the carrier off
to protect the satellite.

Command a Modulator's Async Terrestrial Interface Type
Mod Async Terr Interface Type
0 = No Framing, Async Off
1 = IBS Framing, Async On
2 = IBS Framing, Async Off
0 = 1200
1 = 2400
2 = 4800
3 = 9600
4 = 19200
5 = 50
6 = 110
7 = 300
8 = 600
0 = RS-232, 1 = RS-485
0 = V.35, 1 = RS-422, 2 = RS-232
Command a Modulator's CTS Mode and Polarity
Bit 0 = Polarity
0 = Normal, 1 = Inverted
Bits 1 and 2 = Mode
0 = Always On (factory default)
1 = CTS reflects the state of the RTS Input
2 = CTS reflects CTS Level Remote Command
Bit 3 - 7 = Spares
Command a Modulator's CTS Level
Query Response
Bit 0 = Level
0 = Off, 1 = On – only valid if CTS Control Mode bits
are equal to "2"
Bits 1 - 7 = Spares
Command a Module's Carrier Delay
Unsigned Binary Value in seconds (0 - 255)
Query a Modulator's Configuration and Status
Query Response
See Paragraph B.6. This is the number of configuration
bytes and is an offset to the start of the status block.
