Good morning!
(even if it's not morning when you read this, it's still more cheerful)

I'd like to thank the people who helped me out and answered my questions  
when I was confused about getting my system to current. I got it all to 
compile (compilation lasted 60 hours without errors).

I also got ppp working on the first shot. I just copied my little script 
to start ppp on Linux and changed /dev/ttyS1 to /dev/tty00 and put the 
domain and routers in /etc/resolv.conf. Since some people seem to be 
having problem with ppp, I include here the script I used:

#!/usr/local/bin/bash
/usr/sbin/pppd connect '/usr/sbin/chat -v "" ATZ OK ATDT*70,3988211 
Username: bmarte Password: my_password_here ">" ppp' /dev/ttyS1 19200 
modem crtscts lock defaultroute mru 1500 netmask 255.255.255.0

That's all. Of course it's safer to not put your password right in...
Hopefully this should also work if you use another shell than bash.

Thanks again for the support,
