Hello Bhaskar,
Thank you very much for the Patch.
I had gone back to the 2.4.0 version of PPP where the "persist" option is
running perfect with Kernel 2.6.9.
When I got your Code, I did some research on it.
Unfortunately, there is no function called "disestablish_ppp" in
sys-linux.c in the PPP 2.4.3 version that I have.
The only two functions whose names are similar to this are
"tty_disestablish_ppp" and "generic_disestablish_ppp".
Would you be able to tell me where you found this Patch?
Would you be able to give me the actual patch file, where the line numbers are
mentioned?
Thank you again very much for taking an interest in my Problem.
Yours truly,
Frank
