*S
n Remote Access Attention Character
Where n is an integer between 0 and 126 indicating an ASCII character
[Default is 42, *].
Defines the attention character to request a remote access session. To request a remote
access session using this character, establish a connection and type the attention
character four times in succession (do not type a carriage return). The *A command
sends this sequence automatically.
In normal mode, register S12 sets the guard time that precedes and follows the
attention character sequence. It should be set to the same value on both the originating
and answering modems. Reliable mode uses its own timing and the modem ignores
register S12. During reliable connections, allow a short pause between typing each
attention character, or type AT*A instead.
NOTE
Remote access is available only during a normal connection or during an MNP
reliable connection without data compression.
