Response to
Query
RTC Time TIM= 6 bytes Command or Query.
A time in the form hhmmss, indicating the time from midnight, where:
hh = hours (00 to 23)
mm = minutes (00 to 59)
ss = seconds (00 to 59)
Example: TIM=231259 (23 hours:12 minutes:59 seconds)

EDMAC
Framing
Mode
EFM= 1 byte, 0 or 1 Command or Query.
EDMAC mode in the form x, 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)

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)
that this unit, as the Master, will forward messages for. 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.

EDMAC Slave
Overwrite
OTO= 1 byte, value
of 0 or 1
Command or Query.
One Time Overwrite to EDMAC Slave modem in the form x, where:
0=Off
1=On
Examples:
OTO=1 causes EDMAC Slave modem to be able to accept ONE remote control command locally after
OTO=1 command.
OTO=0 turns off One Time Overwrite, only EDMAC command from EDMAC Master modem will be
accepted by Slave modem.

Channel
ESC= 1 byte, 0 or 1 Command or Query. (IBS and ESC++ feature)
ESC in the form x, where:
0 = Disable the high-rate ESC
1 = Enable the high-rate ESC
IBS ESC may only be enabled when:
1. Both Tx and Rx framing modes are set to IBS.
2. Data rate is not 1544 kbps (as spare overhead bits are not available in this mode).
3. IBS high-rate ESC FAST option is enabled.
