Modem Conguration
If you are behind a private branch exchange (PBX), you may need to enter a dial prex.
This is often a zero. Consult the instructions that came with the PBX to nd out. Also
select whether to use tone or pulse dialing, whether the speaker should be on and whether
the modem should wait until it detects a dial tone. The last option should not be enabled
if the modem is connected to an exchange.
Under Details, set the baud rate and the modem initialization strings. Only change these
settings if your modem was not detected automatically or if it requires special settings
for data transmission to work. This is mainly the case with ISDN terminal adapters.
Leave this dialog by clicking OK. To delegate control over the modem to the normal
user without root permissions, activate Enable Device Control for Non-root User via
Kinternet. In this way, a user without administrator permissions can activate or deactivate
an interface. Under Dial Prex Regular Expression, specify a regular expression. The
Dial Prex in KInternet, which can be modied by the normal user, must match this
regular expression. If this eld is left empty, the user cannot set a different Dial Prex
without administrator permissions.
