When dialing into a ppp account, is it possible to authenticate
manually?  I need to access a ppp account that uses challenge-
response using a harware token.  I am able to do this in FreeBSD
with user-ppp by using the 'term' command to dial (atdt ...) and
authenticate.  Any ideas on how I can accomplish this with NetBSD?
I can initiate the session manually with 'tip' - can I get ppp to
'take over' an existing connection?

Thanks in advance,
Cory.
