HAYES AT COMMAND SUMMARY:
This manual does not attempt to be a primer on the Hayes AT command set.
The commands are, therefore, only summarized below. For most applications,
these commands will not need to be used. Except as noted, all commands
should begin with an “AT” and end with a carriage return (hit the [Enter] key).
There are no “O” as in Oscar commands, only “0” as in Zero commands. For
example, to change the default number of rings from 1 to 3, the command is:
ATS0=2 (the default is 1 ring as the MPU sends ATS0=1 by default to the
modem module).
