Using AT Modem Commands

The Evaluation Daughtercard contains a wireless serial device firmware with optional data filter for
configuring using AT style modem commands. This feature allows devices with an existing AT command
interface to configure the unit, if the AT commands can be properly modified. You must be familiar with
the general operation of AT commands. Note that AT command processing is not enabled by default. Use
the command SET PORT S1 FILTER AT to enable this feature.

All commands begin with AT and are terminated by a new line unless noted below. While standard AT
commands are defined to be 40 characters or less (not including the AT), the server accepts commands
of up to 80 characters.

Standard AT Commands Supported

The following standard AT commands are interpreted by the device server. The data channel must be in
the command mode for commands to be recognized. The data channel will be in command mode upon
power up or reset.

There are two operating modes for the unit when the AT command option is enabled. In command mode,
data received from the serial port is passed to the AT command processor, and responses are returned to
the serial port. No data is sent to any network application, and any data received from the network is
ignored. In data mode, data from the serial port passes to the network application, and vice versa. This
is equivalent to the normal serial port operating mode without the AT command option.

Table 16 describes the AT Commands. Table 17 details the Extended AT Commands that allow the
configuration of the network server operating parameters.
