Wouldn't know where.

NO! Servers supporting it will also deny it. Instead, reply (as said) with a
NAK to the PPP Configuration_Request. And in fact this is correct. If an
authentication protocol should be used is pretty much the choice of the ISP.
So if no Auth_Prot_Req is sent, no authorization is required at all, and if
it is, you can incidate the desired protocol over the standard one.

If you don't do it this way, no wonder most servers don't seem to support
PAP. You must avoid 'double' options residing in as well the sending
Conf_Requests as the receiving Conf_Requests if possible.

Assembly is fast.
And although more difficult concerning complex tasks, still very much fun.
And it gives you complete control over the machine's actions and the
optimization of the code...
