Humm. The kernel ppp module is not getting unloaded. I am using both the
pppd 2.3.11 and pppd-mppe 2.3.10 versions (pppd-mppe has CHAP-80 and MPPE
patched into the code). The user space module does load and unload a lot
due to all the testing we are doing.

I took the CWorthy ncurses interface I wrote for the NWFS tools, and am
using it to write a pppconfig utility that handles modem setup, inittab,
mgetty, options.ttyX, etc. so setting up a dial-in server will be as
easy with IPX and IP as it is in NT.

I have also noticed that pppd is not "kicking" modprobe -v the way it
probably should, and the ppp kernel modules have to be loaded and
configured manually.
