AT Command Set INSYS Modem 336/56k 4.1 (UL)
Command Description
ATD<n>
(Continuation)
‚ Dial tone delay: The modem performs a dial tone delay before it executes
the next character of the parameter string. The delay length is defined in
the S8 registry.
L Last number re-dialing.
; Return to the input mode after dialing. It is added to the end of the dial-
ing string and causes the modem to return to the entry mode when it
reaches “;” (with: message OK). This enables the input of AT commands
even with a receiver off-hook. The additional AT commands can follow in
the same input line after the “;” or they can be transmitted to further in-
put lines. The ATH command will abort the connection and the receiver is
hung up.
S=n Dialing the n-th number from the number pool, which was set up with
the AT&Z<n> command.
! If the character ”!” is a part of the dialing string, the modem will hang up
within the time frame determined in S29 and then goes off-hook again.
^ Suppresses the sending of a ringing tone.
ATD12345; The semicolon (;) causes the return to the input mode after dialing.
Default: Ringing tone is sent for fax operation. No ringing tone for data operation.

ATX3D0W12345
For PBXs, which connect to the exchange line using the prefix 0 (or 9):
First, blind dialing is activated with :X3 (see “ATX3” command), to be able
to dial a leading 0 without hearing a dialing tone. After 0 has been dialed
via: D0, dialing tone recognition can be switched on again using the pa-
rameter: W. The modem thus waits for the dialing tone and continues
with the rest of the dial-up (via :12345) only after hearing the dialing
tone. Waiting for the dialing tone may be omitted. In this case, the dialing
command is ATX3D012345.
