Dear Dave:

But that is my problem.  Shutting down pppd, and doing an ifconfig ppp0 down
before a suspend will not prevent the OS from crashing when I try to use PPP
after my laptop wakes up from sleep mode.  As I stated before, the OS
completely crashes, right away, with a total system freeze.  I suspect the
problem lies with the PCMCIA modem card.  Mind you, I can use the modem
in Win95, after waking up from sleep mode.  Is there something else I can do
(in addition to killing pppd and ifconfig ppp0 down) to shut down the PCMCIA
fax/modem card before a suspend?

BTW, I am running the folowing interfaces, as revealed by an "ifconfig -l":
             ep0 lo0 ppp0 ppp1 eon0
