Is there a standard DUN login protocol?

Hi - Does anybody know (or can direct me to a page) that explains the
"standard" protocol for "dial up networking" to login to an isp?

Using a text terminal, I can see that my ISP asks for 4 things:

1. username
2. Password
3. login Host
4. Select Slip/PPP/Quit from menu

Every script that I have seen only handles the user name and password.
Somehow, windows dun connects properly and is somehow handling those
last 2 prompts (login host and selecting ppp from a menu). I want to
findout what dun is entering into the "login host" field.

BTW - the ISP will not accept a null value in the login host field.
If you type a "return" it gives an error saying "aliasing not allowed"
(whatever that means). I have found that you can type any valid url
in to the login host propmt, such as yahoo.com or google.com. Then
you just select PPP from the menu, and you are in. But I want to know
what dun is doing. There must be a standard out there, otherwise how
does everybody design the connections to be compatible?

I'm using win98 - but any win computer will connect.

Since windows dun is handling the above 4 prompts, there must me a
standard protcol somewhere on the net that can explain what dun is
doing.

Thanks

As I understand it, most ISPs use pure PPP and so the DUN connection starts after your
prompt number 4.

For the few ISPs who give you a choice of SLIP or PPP, they login is unique to them.
That's why DUN provides a Dial-up Scripting extension so that you can get through the
login to the PPP point.

For some sample scripts, search your PC for *.SCP files. You can open them in Notepad.

The CompuServe one sends CIS for the Host Name.

Your ISP could tell you what they are expecting. Based on your testing, it doesn't seem
to matter what it is as long as something is sent.

You are absolutely right about the ISP requiring pure PPP. After some
playing around (I'm actually trying to setup a dial connection on a
UNIX machine), I simply had ppp start exchanging packets right at the
login prompt (ie - no login) and it worked. Of course, authentication
takes place inside ppp with PAP. I guess that explains what Windows
is doing, ie it is not dealing with the username/password/login host,
etc.

Thanks for the help.
