Using AT Commands C-1
Appendix C Using AT
Commands
Syntax
The following guidelines apply to all AT commands, except where
noted otherwise.
♦
All commands, with the exception of +++, A>, and A/, use the
AT prefix and are executed with a carriage return (Enter). For
example, to go off hook with the
Hn
command, you would
type the following:
ATH1
and press Enter.
♦
A command string may be a maximum of 60 characters.
♦
Commands may be typed in upper (AT) or lower case (at), but
not a combination of both.
♦
Missing parameters are assumed to be zero (ATH=ATH0).
♦
A valid command receives the OK response. The ERROR
response indicates an invalid command or parameter.
S-Registers
Change the settings of an S-Register with the ATS r = n command,
where
r
is the register and
n
is a decimal value from 0-255. For
example:
ATS11=50
