Extended result messages,, dial tone detection
The command determines, which message group is sent to the PC by the i-modul
Modem 144/56k 3.0 basic. This is important for PABXs, as a leading 0 or 9 must
often be dialled before a dialling tone is heard on the line.
Blind Dialling (dialling
without detecting the dialling tone) is activated or deactivated according to the
parameter. The detection of the dialling tone, however, can always be enforced
using the parameter W in the
ATD
dialling string (refer to the command
