Description
‚
Dial tone delay: The INSYS Modem 56k Small INT 2.0 performs a dial
tone delay before it executes the next character of the parameter
string. The delay length is defined in the S8 registry.
Last number re-dialing.
L
;
Return to the input mode after dialing. It is added to the end of the
dialing string and causes the INSYS Modem 56k Small INT 2.0 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 input 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 INSYS Modem 56k
!
Small INT 2.0 will hang up within the time frame determined in S29 and
then goes off-hook again.
^
Suppresses the sending of a ringing tone.

For PBXs, which connect to the exchange line using the prefix 0 (or 9):
First, blind dialing is activated by: X3 (see the command „ATX3") 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 parameter: W. The INSYS Modem 56k Small INT 2.0 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.
