It is recommended that you use command names that are easy to
remember later during the configuration. At this point, the
commands are not yet associated with any state.
Parameters can be inserted in commands by enclosing them in
curly brackets, { }. Parameters named inside the brackets are
attempted to be read from the following sources:
- Parameter set for the associated logical interface, that is,
netifX.
- The modem control's own parameter set, for example,
GSM_Siemens_1.
If the parameter cannot be found, the command will be sent to the
modem as it is written.
A built-in delay command can be used to pause the sequence for a
specified period of time (in milliseconds). The delay command
syntax is:
DELAY(TIME_MS)
Non-printing characters can be inserted using the C programming
language syntax, for example:
- \r = carriage return
- \x1B = ASCII character 1BH, that is, <ESC>
- If the command contains quotation marks ("), they must be
entered as \".
Below are examples of valid commands:
- AT\r
- ATV1E1&D0\r
- ATD{isp}\r
- \x7E\xFF\x7D\x23\xC0\x21\x7D\x25\x7D\x23\x7D\x20\x7D\0U
ser request\x79\x7B\x7E
- DELAY(5000)
NOTE The Null (\x00) character is not allowed in the command.
NOTE For a comprehensive set of AT commands supported by your modem,
please refer to the modem documentation.
