Arguments for
Command or
Response to
Query
Command or Query.
Sets or returns how RTS/CTS operates at the main data interface in the form x,
where:
0 = RTS/CTS Loop, No Action
RTS and CTS are looped, so that CTS echoes the state of RTS, but RTS
does not control the ON/OFF state of the carrier
1 = Loop, RTS Controls Tx O/P
RTS and CTS are looped, so that CTS echoes the state of RTS, and RTS
controls the ON/OFF state of the carrier (in other words, the modem will not
bring up its TX carrier until RTS is asserted.)
2 = Ignore RTS, Assert CTS
3 = 1:N system in use.
RTS/CTS ignored (Query only) RTS is ignored, and CTS is asserted
unconditionally.
Example: <0/RTS=0 (RTS/CTS Loop, No Action).
Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns CnC Mode in the form x, where:
0 = Off
1 = On (normal)
2 = APC, C-Band, Side A
3 = APC, X-Band, Side A
4 = APC, Ku-Band, Side A
5 = APC, Ka-Band, Side A
6 = APC, C-Band, Side B
7 = APC, X-Band, Side B
