True.

Yes... it is permanently enabled since August.
debug
kdebug 1

No, mine is a standard serial port external modem, complete, and works
pretty fast with SuSE versions up to 8.2 with the same ISP, phone lines,
computer, and configuration.
Let me see, I reported this in full time ago, this summer. A link to the
thread:
http://lists.suse.com/archive/suse-linux-e/2004-Jul/3411.html

Serial modem, standard hayes, 3COM usr robotics 56K. Connection string:
CONNECT 50666/ARQ/V90/LAPM/V42BIS
- --> Carrier detected. Starting PPP immediately.
Note that the speed reported there is the real speed, modem to outside,
not the speed of the serial port to the computer. I configured it that way
long ago.
The pppd log (not today) shows:

You can see the seconds do match the resets, or seem to... so I disabled
that compression in /etc/ppp/peers/ppp:
plugin passwordfd.so
noauth
#Cer - copied from 'pppoe'
# switch off all compressions (this is a must)
#nopcomp
# this is recommended
#novjccomp
noccp
# because ccp gives errors in the log.
More info? :-)
I'm currently using two computers:
1) A P-IV, SuSE 9.1, pretty fast, with eth connection to #2
2) A P-I, 133Mhz, 32 Mb, SuSE 7.3, connected to the modem, acting as
access router for #1. Only this way can I get normal modem speeds.
