Configuring the AirLink GX440
Rev 1.0 Jan.12 39
• Most commands with parameters can be entered with ? to read the current
value. For example, AT&D? will respond with “2” if the default has not been
changed.
• Optional parameters are denoted with square brackets [ ].
• AT Commands are not case sensitive. A capital “E” is the same as a
lowercase “e”.
• When you are using a terminal connection, if you enter a command which is
recognized by the AirLink GX440, it will respond with “OK”. If the command is
not recognized, the response will be “ERROR”.
• Any commands applicable only to certain model numbers of the AirLink
GX440 will be noted.
Caution: Symbols listed with commands, such as *, /, &, or ?, are part of the command
and must be included. Commands with symbols other than * may require PassThru mode.
