BEWARE: HIGHLY EXPERIMENTAL!
|
||||
---------------------------
|
||||
|
||||
This program is used in conjunction with a isdnd.rc entry similar to
|
||||
|
||||
regexpr = "ULPPP.*call active" # look for matches in log messages
|
||||
regprog = i4brunppp # execute program when match is found
|
||||
|
||||
this one (see also i4brunppp-isdnd.rc).
|
||||
|
||||
i4brunppp _must_ be put into /etc/isdn!
|
||||
|
||||
When an active call is detected, isdnd fires off i4brunppp, which attaches
|
||||
the rbch device used to stdin/stdout and then runs ppp which is given the
|
||||
"-direct" command and the string "inc_rbchX" (where X is the i4brbch unit
|
||||
number) as arguments.
