Package: kppp
Version: 3.0 (KDE 2.0.1)
Severity: wishlist
Compiler: gcc version 2.95.3 19991030 (prerelease)
OS: Linux 2.2.17-21mdk i686 (Linux-Mandrake 7.2)

It could be practital to be able to use different modem strings when connectiog. I use
a ISDN terminal adapter to connect and i would like to choose between PPP and MPPP - this 
could be solved by using two profiles each with a different string and without having to reconfigure 
the TA each time. 
Different modemstrings could also be usefull is a situation where a user has noisy phonelines and as to
remove phones or other devices from the line in order to have a usefull connection. If the 
same user just needs to read or send his mail -opposed to downloading files-  its irritating to remove 
devices from the line. The solution could again be a string that adapts the modem to 
the current line conditions.

Better late than never, i suppose :-)
Personally i dont use a modem or ISDN adapter anymore, but having worked in tech support not so long ago the problem of course still persists. 
An improvement idea related to this bug, would be to have a kppp mode where the line automaticly is probed (only modems)and line speed is locked and written to a profile. The problem with noisy phonelines is rather simple, and is that modems tend to initially negotiate the correct line speed (40000 bps, 41333 bps etc) but during the session increase speed. Assume ideal linespeed is 40000 bps: increasing linespeed from ex. 4000 bps to 41333bps can result in so many transmission errors that line-speed never returns to the ideal 40000bps. Just locking maximum speed to initial nogtiation speed - the 40000 bps - will solve loads of problems. I guess near 80% of modem could be solved this way - this is based on 4+ yeafs experience with modem related problems.

This project is unfortunately no longer maintained.

If a new maintainer wants to step up and take care, the project is archived here:

https://invent.kde.org/unmaintained/kppp

You can just clone it in your private namespace on invent.kde.org and if you have started to work on it and fixed/implemented something get it reviewed and the project unarchived.

Sorry for the inconveniences.
