Some commands may output result information on lines following the command, but the output will
always terminate with either the OK sequence (introduced in the previous section) or the ERROR
sequence (ERROR<CR><LF>).
Some commands may have different results depending on the number of parameters. In general, a
command that sets a parameter(s) can read back its values by issuing the command with no parameters.
To get on-line help with a command, enter the command with a question mark at the end.
To see a list of all commands, use the HELP command.

Configuration Commands
The following commands are standard Raveon commands implemented by the modem.
Command
Command Description
Parameters
Factory
Default
EXIT
Exit command mode, do not open the link connection.
ATDT
Exit command mode and open link. A parameter after the
ATDT command will be interpreted as the link hostname to
use. If there is no parameter, the default host is used, as set
by the ACHN command.
ACCN
Set/read the connect string. 1-16 characters. Set it to X to
have the device pass the carrier’s connect string through.
CONNECT
ACDN
Set/read the no-connect string. 1-16 characters. Set it to X
to have the device pass the carrier’s connect string through.
DISCONNECT
ACEN
Set/read the disconnect string. 1-16 characters. Set it to X
to have the device pass the carrier’s connect string through.
EOF
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). Over-the-
air (throughput) baud rate is set with ATR2 command.
If a PC’s serial baud rate is set higher than the fixed over-the-
air baud rate of the module, hardware handshaking may be
required.
Range: 0
– 7
0 = 1200 5= 38400
1 = 2400 6=57600
2 = 4800 7=115200
3 = 9600
4 = 19200
5
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. This command is only
used on the VHF version of the product. The UHF does not
support w
N
N or W
