Initialization Strings
An initialization string contains several AT commands that are entered
at once to program the modem for a specific application.
The following initialization strings identify essential AT commands
that directly impact modem operation for a particular application. If
you need to modify these strings for your application, make sure
additional commands are inserted somewhere in the middle of the
initialization string. Whenever an &L command is used, it must appear
at the end of an initialization string.
