Description of Arguments
Command or Query.
In a 1:1 system, each modem has its own unique IP address, which
would be used by an external M&C application to address each
modem. The IP traffic uses a different address, and whichever
modem is online, uses this address for the IP traffic.
Format:
aaa.bbb.ccc.ddd
Permitted ranges:
aaa
0-223
bbb
0-255
ccc
0-255
ddd
0-255, but they cannot all be zero.
Other restrictions:
If IP range<24, aaa may not be >191.
If IP range<16, aaa may not be >127.
Example: IPT=010.006.030.002
Query only.
Used to query the unique MAC Address for the modem.
Example: MAC=0006B00001C2
Command or Query.
Defines how RTS/CTS will operate at the main data interface.
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 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 carrier (in order words, the
modem will not bring up its TX carrier until RTS is asserted.
2=Ignore RTS, Assert CTS.
Example: RTS=0 (RTS/CTS Loop, No Action)
