(Instruction
& Qualifier)
Response to Query
Traffic IP
Address
IPT= 15
bytes
numerical
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
IPT=
IPT?
IPT*
IPT#
IPT? IPT=xxx.xxx.xxx.xxx
(see description of
arguments)
MAC Address N/A
12 bytes,
alpha-
numerical
Query only.
Used to query the unique MAC Address for the modem.
Example:
MAC=0006B00001C2
N/A
MAC?
MAC=aabbccddeeff
(see description of
arguments)
Request to
Send
RTS=
1 byte, value
of 0, 1, 2
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)
RTS=
RTS?
RTS*
RTS#
RTS? RTS=x
