(Instruction
& Qualifier)
Response to Query
Traffic IP
Address
IPT= 18 bytes,
numerical
Command or Query.
In a 1:1 system, an external M&C application addresses each modem by its unique IP address.
Whichever modem is online uses this address for the IP traffic in the form aaa.bbb.ccc.ddd.yy where:
aaa=000-223
bbb=000-255
ccc=000-255
ddd=001-255
yy=Subnet Mask Length (08 to 30)
EXAMPLE: <0/IPT=010.006.030.002.24
IPT=
IPT?
IPT*
IPT#
IPT? IPT=
aaa.bbb.ccc.ddd.yy
(see Description of
Arguments)
MAC Address N/A 12 bytes,
alpha numerical
Query only.
Returns the unique MAC Address for the modem.
EXAMPLE: <0/MAC? >0/MAC=0006B00001C2
N/A MAC? MAC=aabbccddeeff
(see Description of
Arguments)
Request to
Send
RTS= 1 byte,
0 thru 2
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 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: <0/RTS=0 (RTS/CTS Loop, No Action)
RTS=
RTS?
RTS*
RTS#
RTS? RTS=x
(see Description of
Arguments)
POCO
feature
(Power-On
Carrier-Off)
PCO= 1 byte,
0 or 1
Command or Query.
When enabled, when a modem is power cycled, it powers up with the Tx carrier setting OFF.
0=POCO disabled (normal operation)
1=POCO enabled – Use with caution!
EXAMPLE: <0/PCO=0 (disabled – normal operation)
