Problem with "persist" on PPP 2.4.3 under Linux Kernel 2.6.9

[Frank Krauss <fmfkrauss@mindspring.com>]

Good day,

I'm having a problem that I can't seem to find any indication of a fix on
GOOGLE for and so I'm hoping that someone on this list can point me in
the correct direction.

I'm running Linux Kernel 2.6.9 on a Pentium 4 using the Caldera Distribution.
I installed PPP 2.4.3 and have been using it successfully for a couple of
days.  My problem with it is the following:

I'm running a 24/7 Server and after every 12 Hour period, my I.S.P,
which is Mindspring/Earthlink, drops my connection.
I have the "persist" option specified to take care of this problem and so
PPP should re-connect successfully.  This worked perfect with my previous
system using Kernel 2.4.22 and PPP 2.4.1.

Unfortunatly, the "persist" option dosn't seem to be working correctly for
me.  At the moment the line gets dropped, PPP now gives me the following
messages in my /var/log/messages file:
   tcflush failed: Input/output error
   Modem hangup
   tcsetattr: Invalid argument (line 962)
   tcsetattr: Invalid argument (line 1001)
   Exit.

This causes me to have to bring up PPP again myself rather than having
the "persist" option work as it should.

This has happened each time for the last (3) re-cycle attempts with the
exact same messages.

If anyone has knowledge of a fix to correct this problem or an option
to use, I would be glad to try them out.

My Environment is:
Computer:     Pentium-4
Distribution: Caldera 2.3
Kernel:       2.6.9
GCC:          3.4.3
GLIBC:        2.3.3
PPP:          2.4.3

Any assistance that someone could give me to solve this problem
would be greatly appreciated.

Yours truly,

Frank Krauss
