FreeBSD-stable, CVSupp'd at ca. 2300 Hrs Fri, June 20, 1997. Made world,
installed new binaries and kernel about 1700 Hrs Sat, June 21.
This ppp gives me this after being up for almost 75 hours.

Killed (had to. Trying to establish a telnet connection to port 3000
is what generated the 5595 'accept' messages...) with -HUP, then
restarted (ppp -auto ispname.)
This ppp connection is:
o called from /etc/rc with /etc/start_if.tun0 which looks like
this:
chat "" ATZ OK AT\>Z OK AT\>D0=`date +%m%d%y` OK AT\>D1=`date +%H%M%S` OK < /dev/cuaa1 | tee /dev/cuaa1
echo 'Sleeping 45 seconds to wake up ISDN connection...' && sleep 45
if [ -f /usr/sbin/ppp ]; then
/usr/sbin/ppp -auto -alias spiritone-isdn-1
fi
o Works flawlessly otherwise.
The PID of the process was 51. (Probably doesn't matter.)
The /etc/login.conf has been modified slightly (root and daemon have
inifinity for all limits.)
Now, for the most important stuff.
This is an OLD system. 486DX/120 (Actually it's an AMD 486).

One last thought.
The PPP connection is on an ISDN connection (Motorola BitSurfr Pro, ISA)
that gets setup by DOS on reboot. (Ugly. Has to be done manually; then
after the card is setup (PNP), I do the three-finger salute.)
IRQ 15 is the 'Data Port' IRQ as set up with the CardSet program.
My USR 33.6 Data/Fax modem is plugged into one of the analog ports on
the BitSurfr.
Thanks in advance for any help.
