INSYS Modem 336/56k 4.1 (UL) AT Command Set
Command Description
ATX<n> Extended result messages, dial tone detection
The command determines which group of messages the modem sends to the PC. This is
important for PBXs, as often a leading 0 or 9 must be dialed before a dialing tone is heard
on the line. Blind dialing (dialing without detecting the dialing tone) is activated or deac-
tivated according to the parameter. The detection of the dialing tone, however, can al-
ways be enforced using the parameter W in the ATD dialing string (see command ATD).
In the mode AT+FCLASS=1,2, the modem always sends the message CONNECT to the
PC without specifying the transmission speed.
ATX0 No detection of the dialing tone, i.e. an unsuccessful dialing attempt leads
to the message NO CARRIER.
No detection of the busy signal, i.e. when calling a busy line the message
NO CARRIER is displayed. The message is displayed without specifying
the speed.
ATX1 As ATX0, but the CONNECT message contains the speed specification.
ATX2 Dialing tone detection is active, i.e. a dialing attempt without the pres-
ence of a dialing tone leads to the message NO DIALTONE.
No detection of the busy signal, i.e. when calling a busy line the message
NO CARRIER is displayed.
ATX3 No detection of the dialing tone, i.e. an unsuccessful dialing attempt leads
to the message NO CARRIER.
Busy signal detection active, i.e. when calling a busy line the message
BUSY is displayed.
ATX4 Dialing tone detection is active, i.e. a dialing attempt without the pres-
ence of a dialing tone leads to the message NO DIALTONE. (default)
Busy signal detection is active, i.e. when calling a busy line the message
BUSY is displayed.

(created using the AT&W1 command) is loaded into the current modem
configuration.
