Command Summary

·

Type commands in either upper or lower case. Do not use a
combination of upper and lower case characters.

·

Use the Backspace key to delete errors. Note that the original AT
command is stored in the modem buffer, and cannot be deleted.

·

Some commands have numeric options. If these commands are
invoked without a numeric option, the modem will assume option
0 (zero). For example, when the command

ATB is invoked, the

modem will assume command

ATB0 was intended.

·

All commands begin with the

AT

prefix, and are invoked by

pressing [Enter] (Carriage Return). The only exceptions are the
A/ command (Repeat previous command) and +++ (Exit to on-
line command mode).

·

The maximum command length is 40 characters. This does not
include the

AT prefix, Carriage Returns, or spaces.

Note:

All defaults are based on the &F1-Hardware Flow
Control template loaded in NVRAM.

Defaults are marked with an asterisk (*).
