Initial Response To The AT Command
After power is applied to the module, the module performs a power-up self-test. The self-test
completes within one (1) second. When queried with the AT command, the module responds
with one of the following result codes:
l
OK signifies that the module is ready, that it correctly interprets the AT command, and
that it has executed the command.
l
ERROR signifies that the module does not understand the command or that the
command is invalid.
Entry AT
Response OK Command valid: module is ready
The module must be in AT Command mode when any command is entered (with the
exception of the online escape sequence). Commands entered when the module is in On-line
mode are treated as data, and are transmitted as such to the receiving module. (i.e. If the
module is in PPP or SLIP mode, AT commands cannot be entered.)
Sending An Initialization String To The Enabler
IIIG-BGA Module
The following example provides the sample AT commands and responses for the following
initialization tasks:
l
Reset the module to the factory defaults
l
Disable character echo
l
Transmit Result Codes
l
Set the module to Verbose mode (to display result codes as words)
l
Set the DCD to match the state of remote modem
l
Ignore the DTR
Entry AT&FE0Q0V1&C1&d0 Initialization string
Response OK Command is valid
Entry ATSO=1 Auto answer on 1st ring
Response OK Command is valid
