ActionTec 56K Internal PC Modem User Manual page 38

Unlike Windows 95/98, there is no set configuration for the modem itself. The mo-
dem is regarded as another serial port attached to the computer. Therefore each pro-
gram must provide its own initialization string when using the modem. Setting the
call waiting feature changing the initialization string (often ATZ, by default) to in-
clude a S10=n, where n is one of the settings available above.
With the setcw.tcl program
This utility provides a graphical way to modify the call waiting setting for KPPP,
ppp-on scripts, and linuxconf. It uses tcl/tk, and the user must have wish installed.
Step 1 Run the program by typing:
setcw.tcl
and pressing ENTER.
Step 2 The program will detect if each of those configurations exist and the user
has read/write access to the necessary files. The configurations that exist
will be checked.
Step 3 Change the setting by selecting one of the three radio buttons at the top
and clicking Set.
Step 4 If you get a "Invalid kppprc file" message, it means that the program did
not find an "InitString=" entry in the file. This can be generated by open-
ing up the Modem Commands window from within kppp.
Step 5 Click Exit.
ppp-on Scripts
The change is actually in the /etc/ppp/ppp-on-dialer script. The script has no line
that contains an initialization string, so one needs to be added. The line should go
right before the line that says:
OK
An example of what should be added is something like this:
''
Be sure to put the \ at the end of the line, since chat takes all of its arguments in one
line. (The \ quotes the invisible carriage-return character.)
