AT Commands
In most cases, you will not need to type AT commands manually.
However, there may be some occasions when you will need to do
so.
This chapter describes AT commands for data mode. Fax
commands are taken care of by application software.
AT command formats
The format for entering AT commands is:
ATXn
where X is the AT command, and n is the specific value for some
of the commands. After you type in the command, press
Enter .
Any command issued is acknowledged with a response in either
text or numeric values known as result codes.
All commands and command-values accepted by the modem are
described in this section; any entry other than those listed results in
an error.
If no value is entered for n, then the command defaults to a value
of n=0.
