Force AT Mode on

AT command mode may be forced to be enabled when a RS232 hardware control line is brought high. The 
signal levels (High/Low) described here are RS232 levels. If you are using just a SItePlayer Module, the logic 
levels will be inverted. When the line is brought low, AT mode is exited and SitePlayer resumes operating in 
its previous mode.

None

 - AT mode forcing is disabled (default).

DSR

 - AT mode is forced when DSR is high.

DCD

 - AT mode is forced when DCD is high.

RI

 - AT mode is forced when RI is high.

When AT command  mode is forced, SitePlayer will act as if it is in AT mode and start accepting AT com-
mands. If SitePlayer has Server mode enabled, it will continue listening for connections and thus you may 
get a 

CONNECT

 or 

NO CARRIER

 message. If SitePlayer has Client mode enabled, it will continue to attempt to 

connect to the remote end and you may also get a 

CONNECT

 or 

NO CARRIER

 message.

SitePlayer polls every tenth of second (1/10s) for force-AT-mode control lines to change. The above input 
parameters may take up to one tenth of a second before they are noticed. This means, for example, the 
changes in the serial port line states may take up to a tenth of a second before they are detected. The serial 
hardware lines should, therefore, be kept constant for at least a tenth of a second.

You should make sure that these control lines do not interfere with the 

Server Connects or Client Connects/

Disconnects

 control lines. You should choose different lines for both these functions.
