Command Mode
Command Mode is used to program and configure the modem. This mode is separate from data mode
and will not transmit received data over-the-air, instead executing commands detailed in this manual.
7.1
Command Mode Encoding and Line Format
In Command Mode, all characters are ASCII encoded. All output lines will use the standard network line
ending, CR+LF (ASCII 0x0D followed by ASCII 0x0A).
Inputs lines may use either CR, LF or CR+LF line endings.
7.2
Entering Command Mode
The
modem may be put into a Command Mode, by entering a sequence of three plus characters (+++),
called the Entry Sequence. To keep the modem from unintentionally entering the Command Mode
because of the Entry Sequence occurring in a stream of data entering the modem, there must be a
pause in the data stream before the Entry Sequence as well as a pause afterwards. If either pause is
missing, the modem will not enter the command mode. The pause length is configurable, by default it is
500ms.
When the modem first enters the Command Mode, it will output the base model number along with the
OK sequence:

OK
Once in command mode, the instructions in the following sections can be followed to continue radio
configuration.
7.3
Using Commands
To execute a command, send the command name and any parameters separated by spaces, followed by
a line ending character. For example, to use the ATAPN command to set the access point name (APN) to
1234, send:
ATAPN 1234<LF>
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.
