[Linux-users] pppd problem

[Bob Hemus]

I had my BestData USB modem working like a champ 'til I tried to get an
icon to initiate it.  Now it's trashed.  Right this minute I'm using it
on SuSE 10.1.  I'm having trouble with my Ubuntu 7.04, which by the way
picked it up right off the bat.

I ran pppconfig and used /dev/ttyS0.  Here is my dmesg message;
Hemus:~ # dmesg | fgrep tty
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
cdc_acm 3-1:1.1: ttyACM0: USB ACM device

I didn't ln -s to anything.  The 'phone rang and I got this error 
Error while Fetching Mail. 
Host lookup failed: sisqtel.net: Name or service not known

Then I ln -s ed the modem and ttyACM0 and here is the plog report;

bob at bob-desktop:~$ ps aux 

I tried kill 9052 
Nuthin...

Earlier in my excursions I also had an error message
concerning /etc/ppp/peers and/usr/share(?)/  don't recognize .dev/modem

Collins, you're using Ubuntu, got any ideas?
Thanks for the brain help.
