Well, traceroute doesn't hang, prints out a bunch of asterisks.
And yes, I've already turned on debug for pppd. Following, I'm trying to clear out the entire situation:

Code:
1a) Routing table on Windows, before the connection:

And this is the connection phase where all seems going well, otherwise I don't think pppd could exit with no errors:

Code:
localhost ppp # cat dial_winnt 
#!/bin/bash
# Call the Windows RAS Server
/usr/sbin/pppd file "/etc/ppp/options.nt"
# Wait for a callback from the Windows RAS server
/usr/sbin/pppd file "/etc/ppp/options.callback"

localhost ppp # ./dial_winnt 
Serial connection established.
