You can use syslogd to log messages to some remote server (if you have
an ethernet connection). I don't remember the necessary options right
now, I think it's in the busybox documentation.

You can't give a password on the pppd commandline. If you use pap, you
need a file "/etc/ppp/pap-secrets':

<username> * <password> *

You will need the following options (preferrably in /etc/ppp/options):

#debug ... for debugging only
noauth 
local 
crtscts
noipdefault
defaultroute
connect <your chat script file>
user <your username, same as in pap-secrets>
usepeerdns

You can start ppp with "pppd ttyS1 &"

Regards,

Erwin
