Query
(Instruction
Code and
Qualifier)
Response to Query
Configuration
Load CLD= 1 byte Command only.
Causes the modem to retrieve a previously stored modem
configuration from Configuration Memory location defined by the one-
byte argument (0 to 9).
Example: CLD=4 (retrieve modem configuration from location 4)
CLD=
CLD?
CLD*
CLD# N/A N/A
Configuration
Save CST= 1 byte Command only.
Command causes the modem to store the current modem
configuration in Configuration Memory location defined by the one-
byte argument (0 to 9).
Example: CST=9 (store the current configuration in location 9)
CST=
CST?
CST*
CST# N/A N/A
RTC Date DAY= 6 bytes Command or Query.
A date in the form ddmmyy (international format), where
dd = day of the month (01 to 31),
mm = month (01 to 12)
yy = year (00 to 99)
Example: DAY=240457 (April 24, 2057)
DAY=
DAY?

DAY# DAY? DAY=ddmmyy
(see Description of
Arguments)
EDMAC
Framing
Mode EFM= 1 byte, value of
0 or 1 Command or Query.
EDMAC mode, where:
0=EDMAC OFF (Idle Mode)
1=EDMAC ON (Master Mode)
2=EDMAC ON (Slave Mode, Query Only)
Example: EFM=1 (EDMAC Enabled as Master)
EFM=
EFM?
EFM*
EFM# EFM? EFM=x
(see Description of
Arguments)
EDMAC
Slave
Address
Range ESA= 4 bytes Command or Query.
EDMAC Slave Address Range - sets the range of addresses of distant-
end units (modems or transceivers) for which this unit, as the Master,
will forward messages. Only values which are integer multiples of ten
are permitted. (0010, 0020, 0030, 0040 etc.)
Example: ESA=0090
This command is only valid for an EDMAC master. When used as a
Query, it may be sent to an EDMAC slave, which will respond with the
appropriate address.

Channel ESC= 1 byte, 0 or 1 Command or Query.
(IBS or ESC++ parameter)
Turn ESC on or off, where:
0=off (disable high-rate ESC)
1=on (enable high-rate ESC)
IBS ESC may only be enabled when:
1. Both Tx & Rx framing modes are set to IBS.
2. Data rate is NOT 1544Mbps (as there are no spare overhead bits)
3. IBS high-rate ESC FAST option is enabled.
