APPENDIX A: AT COMMAND CODES

Normally the GUI is the best way to configure, control and interrogate a local Orion unit. However, if you want to use your own equipment and software to do this, you can use the serial port to send ASCII AT commands and receive replies, which are listed in this Appendix.

The modem is configurable via the same port as is normally used for data. To configure it, you need to connect a terminal or equivalent to the port, and to switch the modem into Command Mode by sending a special code. The next three sections explain how to enter Command Mode, the syntax used during configuration, and how to exit Command Mode and return to sending and receiving data normally. The remaining sections list the commands in detail.

In this part of the manual, characters which are sent or received literally through the port are shown thus: ATB0. Non-printing characters such as the Enter key, or the carriage return and line feed characters, are shown thus: <enter>, <CR>, <LF>.

Where <enter> is shown, the modem expects to receive the characters <CR><LF> (codes 0A 0D hex). Most terminals send these codes in response to the <enter> key, but the keystrokes <ctrl+M><ctrl+J> are equivalent.

Important: Any configuration changes made will only be saved to the non-volatile memory when you issue a write command (AT&W). Otherwise, the modem will return to its former settings when it is powered down.

Entering Command Mode (+++)

Command Mode is activated with the string

[wait]+++[wait]<enter>

where [wait] is a period when no data is sent to the modem. It must be at least the period set by ATS154=, default value 10ms.

The modem responds with:
