Don't work in my case. It would create the telnet session.

In order to find out the reason, I played following little
experiment: I loaded the EtherPPP driver, then load the NCSA
telnet and make a telnet session to my shell account. It works
fine. I quit the NCSA telnet, then load it again. Once again I
make a telnet session to my shell account, it also works fine.
Then I quit the NCSA telnet and load MS-kermit by typing kermit,
do NOTHING, then quit MS-kermit by typing quit. I load NCSA
telnet, at this time the NCSA do not work and complain that it
can not initialize the network layer.

I also play the second experiment: I loaded the SLIP8250 SLIP
driver, than run the MS-kermit and make a telnet session to my
shell account, it works fine. I quit MS-Kermit, then run the KA9Q
telnet and make a telnet session to my shell account, it also
work. Then I quit KA9Q and run the MS-kermit to make a telnet
session to my shell account. It also works fine. Noted that I
never unload the SLIP8250 driver, when I switch between MS-kermit
and KA9Q.

I also do not unload the EtherPPP when I switch between MS-kermit
and NCSA telnet.

After loaded the EtherPPP, I have no problem to load the NCSA
telnet and make the telnet session and then quit from it multiple
times without unload the EtherPPP.

>From the above experiments, it suggests something has be changed
when the MS-Kermit is loaded and then be unloaded. It make me can
not switch to NCSA if I run MS-kermit first. Since EtherPPP work
with MS-kermit in your lab, so it may be caused by something in
my particular software and hardware combination. It looks it is
my time to give up my try to make PPP work in my PC once again.
