Raveon RV-M7-UC-GX Quick Start Manual page 6

This pin-out allows it to be directly plugged into a computer's 9-pin serial
port using a conventional 9-pin RS-232 serial cable. To connect it to a
modem, or peripheral that has a serial port, you will need a "null-modem"
cable.
6. Configuring the M7 GX
6.1. Overview
There is a "Command Mode" used to program and configure the M7 GX.
In the Command Mode, the M7 GX modem accepts commands via the
serial port. The M7 GX modem may be put into a "Command Mode", by
entering a sequence of three plus characters (+++) using serial
communications software such as HypterTerminal.
When the M7 GX modem first enters the Command Mode, it sends the
phrase "RV-M7" out it serial port, and then an "OK".
6.2. Setting a Parameter
To set a parameter in the M7 GX modem, enter the Command Mode as
described above, then enter the proper command, a space, the
parameter, and then the enter key. For Example, to set the destination
address (DT parameter) of the M7 GX modem to 25, enter the following
command: ATDT 25 <CR>.
6.3. CONFIG Button
There is a small push-button inside the M7 to assist. This "CONFIG"
button may be pressed at any time, and forces the M7 GX into a known
state. The CONFIG button is located inside the M7 GX.
The default settings that the M7 GX will revert to when the CONFIG
button is pressed are:
1. Serial port 9600 baud, 8 data bits 1 stop, no parity
2. Serial port flow control is off.
3. ATCT setting set to 60000 (60 second time-out)
Even though the serial baud rate reverts to 9600 baud when the
CONFIG button is pressed and the IO port is RS232, it will revert back to
the settings programmed into the M7 GX once the Command Mode is
exited.
