4.4.2 Configuring the Radio
The radio uses s-registers to alter the configuration profile. Each s-register contains a decimal value, an
ASCII character or an ASCII string. The interpretation of each value differs with each s-register.
The radio allows the contents of the s-registers to be saved to non-volatile memory using the
AT&W
command. The entire configuration profile will be retained after the radio has been powered off.
The radio also has factory default settings stored internally, allowing all communication settings and s-
register values to be set to the factory default configuration. The factory defaults have been selected so most
users will be able to make immediate use of their radio, with minimum changes. The default settings are
listed in Appendix D on page 105.
Factory defaults can be restored using the
AT&F
command.
The
AT&V
(view) command outputs the current configuration of the radio.
The complete AT command reference is provided in Appendix C on page 86, while the use of Hayes AT
commands to establish dial-up networking connections is discussed in section 5.3.3 on page 34.
