Description

cutes the next character of the parameter string. The delay length is
defined in the S8 registry.

Last number re-dialing.
;
Return to the input mode after dialing. It is added to the end of the
dialing string and causes the moden to return to the entry mode when
it reaches “;” (with: message
OK
). This enables the input of
AT
com-
mands even with a receiver off-hook. The additional
AT
commands
can follow in the same input line after the “;” or they can be transmit-
ted 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 modem will hang
up within the time frame determined in S29 and then goes off-hook
again.

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 modem thus waits for the dialing tone
and continues with the rest of the dial-up (via: 12345) only after hear-
ing the dialing tone. Waiting for the dialing tone may be omitted. In
this case, the dialing command is
ATX3D012345
.
