How do I find out if my ISP uses SLIP or PPP?

Intriguing. Please clarify. Is the card synchronized with the server,
or...actually, is it a card as in credit card or as in network card?
Does the server emit an encrypted password for which you have the key?

Dial in with PPP. If it works, then it is PPP. If not, try SLIP. :)
However, if security is so crucial, it seems they would prefer PPP
because (I think I read) it is more secure.
