4.3 Terminal Menu Interface
The terminal menu provides access to all configuration parameters in the radio. There are three methods for
accessing the terminal menu:
1.
Execute the
AT?
command at the Hayes AT command interface. See section 4.4 on page 13 for
information on executing AT commands.
2.
Dial a remote radio’s menu system using AT commands. See section 5.3.3 on page 34 for more
information on connecting to remote radios via AT commands. When a menu system is accessed
remotely its functionality is limited in order to prevent a configuration change that would break the
connection.
3.
Select mode 6 on the front panel interface. See section 4.5 on page 16 for information on selecting
front panel modes.
The terminal menu has the following features:
The terminal menu can be password protected to prevent unauthorised users for reading or changing
the radio configuration.
If a terminal menu is enabled, but there is no input for a configurable period of time, then the
terminal menu will disable itself. By default the terminal menu is disabled after 15 minutes.
Only 1 terminal menu can be available at any one time. This is done to prevent multiple users from
changing the configuration of a single radio at the same time.
The full terminal menu reference is provided in Appendix B on page 68.
4.4 Hayes AT Command Interface
The RFI-9256 supports many Hayes compatible commands enabling the user to fully control and operate the
radio, and in most cases emulate public switch telephone network (PSTN) modems.
Hayes commands may be entered manually through a terminal or automatically through dial-up network
applications and scripts. Most commands, with exception of the ‘%’ register and connection commands, may
be concatenated into a single command string. Commands or command strings must be terminated with a
carriage return, produced by the enter key.
4.4.1 The AT Commands
THE ATTENTION CODE
The attention commands are a group of commands recognised by the radio. All attention commands are
prefixed by the letters AT, and are referred to as AT commands. For example, the command:
ATI3<CR>
Causes the radio to return its firmware version information:
