Data Communication and Host Modes

AT Mode

Using a terminal connection, AT commands are used to configure the modem, command it to do
something, or query a setting. For a full listing of the AT commands, refer to page 62. Wireless
Ace is a graphical user interface for most AT Commands.

AT commands must always be terminated by (ASCII character 0x0D), a carriage return
(pressing enter on the keyboard). Some may also include a new line or line feed .

If E=1 (Echo On), the AT command (including the terminating played (output) before any responses.

Two settings affect the format of AT command output: V (Verbose) and Q (Quiet).

If Q=1 (Quiet On), no result codes are output whatsoever, so there is no response generated by
a (non query) command.

If Q=0 (Quiet Off), result codes are output. The format of this output is then affected by the
Verbose setting.

If Quiet mode is off, the result code is affected as follows:

For V=1 (Verbose mode), the textual result code is surrounded by a carriage return and new
line. Any AT query response is also surrounded by a carriage return and new line.

For V=0 (Terse mode), a numeric result code is output with a single trailing carriage return (no
new line is output), while any AT query response is followed by a carriage return and new line
(there is no preceding output).

For example, possible output to the AT command "AT" with carriage return (assuming quiet mode
is not on) is:

carriage return - if V=0

carriage return and new line OK another carriage return and new line - if V=1

PassThru Mode

Issuing the "AT\APASSTHRU" from a terminal emulation enters this mode. The modem responds
with OK, at which point a direct connection to the internal hardware is established.

With Wireless Ace, you can configure a string of AT commands to be sent to the PinPoint-E when
it enters PassThru and other PassThru settings.

In PassThru mode, the PinPoint-E does not behave normally, all port communication is passed
directly between the internal hardware and the computer connected directly to the modem. This
mode can be used to configure hardware-specific settings (for example, provisioning, trouble-
shooting, etc.).
