AT Commands
This section lists all the modem AT commands in alphabetical order. A command
argument printed in bold is the command default setting. In most cases, you will not
need to change the default setting.
NOTE
The A/ command is the only command not preceded by “AT” and not followed by
a carriage return.
A/ Repeat Last Command
Re-executes the last command immediately.
A Answer
Forces the modem to go off hook in answer mode, regardless of the value of register
S0. If result codes are enabled, your computer displays RING (long form) or 2 (short
form) when it receives a call.
$An Auto-Answer Auto-Logon
Performs a logon sequence (created using the $Ln command) after accepting a call
from a remote system. If the sequence is successful, a connection to the remote system
is established.
Sequences 1 to 4 are predefined and used as default logon sequences during Dial
Access Security. Sequence 5 is predefined and used for Connection Password
Security. Sequence 0 disables auto-answer auto-logon.
