Hello,
Thank you for the detailed instructions, here is some more
information.

If I start the dial up with `wvdial <config name>` I get this in the
console:
[root@localhost modem]# wvdial HTppp
--> WvDial: Internet dialer version 1.53
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATM3
ATM3
OK
--> Modem initialized.
--> Sending: ATDT077100000

ATDT077100000

User Access Verification
Username:
--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Sun Apr 11 14:10:56 2004
--> pid of pppd: 5283
Note the lines with '<============'. Those indicate that my modem IS
talking to my ISP, because 'HiNet, HT d.d.' is the name of the ISP,
and I did not enter that name anywhere. This must be coming from the
remote dial-in server.
In /var/log/ppp.log I get only this:
Apr 11 14:10:56 localhost pppd[5283]: pppd 2.4.1 started by root, uid
0
Here are some of the relevant configs from my ifcfg-HTppp file:
BOOTPROTO=dhcp <==== is this wrong? what should I set it to?
ONBOOT=no
CCP=off
PC=off
AC=off
BSDCOMP=off
VJ=off
VJCCOMP=off
LINESPEED=57600
MODEMPORT=/dev/modem
DEMAND=no
DEFROUTE=yes <==== is this wrong? that should set the
routes, no?
PERSIST=no
PAPNAME=samofix
There are no errors in any of the logs.
However, when wvdial connects to the remove dial-in server, there are
also no routes set, no IP for my computer, and no DNS servers.
Then I tried using `ifup-ppp0` and I got this in the ppp.log:
pr 11 14:37:23 localhost ifup-ppp: pppd started for ppp0 on /dev/modem

So it looks like the modem connected, and then something blew up and
killed pppd.
In the /var/log/messages.log I saw this:

This also shows that the modem first connected, and then something in
pppd and/or kernel blew up. I see that the ppp-related kernel modules
are mentioned.
These are the modules that I loaded with modprobe ppp_generic.o (I
think that is the module I loaded, but I'm not 100% certain now..
maybe it was ppp_deflate):
ppp_deflate 4504 0 (unused)
zlib_deflate 21368 0 [ppp_deflate]
ppp_generic 24444 0 [ppp_deflate]
slhc 6740 0 [ppp_generic]
Am I missing a module that is required for ppp to work?
Any help would be very much appreciated.
Thank you.
