5. Command Mode Commands
5.1. General Command
These commands apply to the general configuration of the M8S, and are
applicable in both the data modem mode and paging mode.
Command Command Description Parameters
Factory
Default
ATAK
Enable/Disable ARQ – When ARQ is enabled, this modem will
automatically send an ACK packet back to a modem that sends
it data. 0=off, 1=on. Range: 0 – 1
0 (no AKCs
sent)
ATAT
Silence AFTER Sequence - Sets period of silence after the
command sequence characters in mS.
Range:0 – 1000
(mS)
500
ATBD
Baud Rate
– Sets serial com port baud rate (bps). Type the
range index (0-7) or the actual desired baud rate.
Range: 0
– 7
0 = 1200 5= 38400
1 = 2400 6=57600
2 = 4800 7=115200
3 = 9600
4 = 19200
3
AFDC
Audio input DC ofset – The DC bias level on the audio input in
millivolt. Adjust this setting so the audio transmissions are on
the center of the channel. Set to 0 to have the M8S auto-detect
the average.
Range: 0-3300
mV
1650
AFLVL
Audio input level gain – internal gain of the audio input signal,
in % . Adjust this setting for the audio input deviation level.
Range: 0-2000%
mV
100
AFLIM
Audio deviation limit – Sets the peak audio deviation limit for
TX audio in the audio pass-through mode. In % of data
deviation 100% limits audio to same as data. . Range: 0-300%
100
ATBT
Silence BEFORE Sequence – Sets period of silence before
the command sequence character in mS.
Range: 0-1000
mS
500
ATBW
Set/Read IF Bandwidth - Sets the IF bandwidth to narrow (N)
or wide (W). Narrow is for 12.5kHz channels, and wide is for 25
or 30kHz spaced channels. N or W
N
ATCD
Carrier Detect Threshold – Read/set the carrier detect
threshold, in dBm. -113 means -113dBm.
-113
-120 to -60
ATCH
Configure Hardware Flow Control – Enable (1) or disable (0)
flow control. When enabled, the modem will monitor the RTS
line, and if it is negated, stop sending data out the serial port. If
disabled, the modem will ignore the state of RTS, and always
send out serial data characters.
1 = Enable
0 = Disable
0
ATCI
Handshaking Invert – Used to invert the RTS handshaking
signal. 0=normal, 1 = inverted.
1 = Invert
0 = Normal active low.
0
ATCM
Command Mode – This command sets the way command
mode can be entered. ATCM 1 will follow the RTS line – ATCT
and EXIT command are still intact
0 = “+++” mode
1 = RTS line
0
ATCT
Command Time Out – If no valid commands have been
received via the serial port within this time period (in
milliseconds), modem returns to normal operation mode from
Command mode. If the CONFIG button inside the
M8S is
pressed, this parameter will be automatically set to 60000.
Range: 100-60000mS 60000
AT
E
Echo
–
Character echo set on (E1) or off (E0). This applies to
the Command Mode only.
Range: 0 , 1 1 (echo)
