COMMAND DESCRIPTIONS
AT Commands
(1) Command format
AT commands begin with <AT> or <at>. Character strings to a carriage return code are interpreted as commands
to be executed successively. A result code is returned to DTE after the completion of interpretations.
AT
Characters
CR
LF
However, the commands of A, D, Dc, On, Zn, Ax, &Tn and &Zn must be set at the end of the sequence of
commands.
Any commands set after those commands are ignored.
The maximum command character string is 40 characters (space <20h> is ignored).
Input characters can be deleted by a backspace function (a cord is changeable).
<CR> is a Carriage Return code (changeable).
<LF> is a Line Feed code (not mandatory and changeable).
Both capital and small letters can be recognized with the exception of At and aT. The communication with the
terminal when inputting commands is handled as an asynchronous mode, and the character format is checked
automatically as soon as <AT> or <at> is input.
This device cannot be guaranteed for normal operation when character strings or parameters not listed below are
input.
(2) Terminal data speed and character format
The communication mode to DTE with the V.24 interface is as follows:
Terminal data speed: 9600/2400/1200/300 bps
