Basic "At" Command Set - ZyXEL Communications Omni TA128 User Manual

Chapter 16 - AT Command Set Reference
Exceptions to this are A/, A>, and +++. These commands are not preceded by AT, or
followed by any more characters.
A/ re-executes the last command once
A> re-executes the last command once or repeats the last call up to 9 times
until aborted by pressing down on any key on the keyboard or front panel
or until a successful connection with a remote modem has been made.
+++ is the escape sequence code that is entered in data state to return the
modem to command state. The modem will accept AT commands only
while it is in command state.
The AT command prefix may be typed in either upper 'AT' or lower case 'at'. Do not
use a combination of upper and lower cases in the prefix.
The following tables list all of the AT commands supported by the Omni TA128. An
asterisk * following a command option or value indicates that it is a default setting when
the modem is shipped.
