Can't stay connected

[Sean_Foster]

I use KPPP to connect and everything seems fine but soon after opening a browser window (which never loads), I am disconnected with an exit code 16. Here is my PPP-logfile:

As for hardware and settings, I am using a Creative Modemblaster V.92 (winmodem) with the linuxant driver. I have commented out the auth and lock in /etc/ppp/options.

I have been able to connect once before but not anymore. Any ideas as to what is causing the SIGHUP? Any help would be greatly appreciated.

Got exactly the same error message many times here on kppp.
Check the following 7 files:
/etc/chatscripts/ (2 files)
/etc/ppp/chap-secrets, pap-secrets, options
/etc/ppp/peers/kppp-options, provider
or better still: use pppconfig to configure and 'pon' & 'poff' to
connect/disconnect.

Problem solved so far. After checking the above 7 files, I found some inconsistencies in usernames and passwords, but I fixed it.

Also, I made a few changes from within KPPP. One thing I discovered was that if a modem does not support hardware flow control, this error can occur, so I set it to software flow control and that seemed to do it. A winmodem . . . I should have known.

Thanks for the help, tomt.
