ATXn Extend ed Result Codes. This command selects which subset of the result messages
will be used by the DIVAT/A to inform the DTE of the results from commands.
n=0 Provide basic result codes: sends only OK, CONNECT, RING, NO CARRIER, ERROR,
and NO ANSWER.
n=1 Provide basic result codes and appropriate connection speed (e.g., CONNECT
2400, CONNECT 19200).
n=2 Provide basic result codes, connection speed, and DIALTONE detection.
n=3 Provide basic result codes, connection speed, and BUSY signal detection.
n=4 Sends all messages (default).
n=5 Displays the calling number as follows:
RING
FROM: calling
(if the remote number is not known the message UNKNOWN is displayed)
n=6 Displays information about the call. The following format is used:
RING [(cip)] called [;calling]
Where (cip) is CAPI 2.0 compatible information profile. It is only displayed if
available. When displayed it always appears in parenthesis.
Where called is the called number. It is always displayed.
Where ;calling is the number that is calling. It is only displayed if available. When
displayed it is always preceded by a semi colon “;”
AT&D n Data Terminal Ready. Controls interpretation of the Data Terminal Ready (DTR) input.
n=0 Ignore status of DTR signal.
n=1 Monitor DTR signal: when an on-to-off transition of DTR signal occurs, enter the
command state. Return to the online state when the ATO command is issued.
n=2 Monitor DTR signal: when an on-to-off transition of DTR signal occurs, hang up
and enter the command state (default).
n=3 Monitor DTR signal: when an on-to-off transition of DTR signal occurs, hang up
and reset.
n=9 Monitor DTR signal: when an off-to-on transition of DTR signal occurs,
automatically dial the stored telephone number 0.
n=11 Monitor DTR signal: when the DTR goes up, dial pre-stored number. Hang up
connection when DTR goes down. (Combination of AT&D2 and AT&D9).
AT&K n Flow Control. Enables and disables flow control so that data is stopped and restarted
when buffer space becomes available.
n=0 Disables flow control.
n=3 Enables RTS/CTS flow control (default).
n=4 Enables XON/XOFF flow control.
n=6 Enables RTS/CTS and XON/XOFF flow control.
AT&S n Data Set Ready. Data Set Ready (DSR) controls the behavior of the DSR output.
n=0 DSR always on (default).
n=1 DSR always on after protocol is connected.
