Since you are actually connecting to the ISP and entering the user id and password, I would suspect you have a wrong setting.  Possibly in the encryption area.  Be sure you are matching what the ISP is expecting.  Compare "neat" settings to these settings and see if anything is different.

When setting up a dial-up connection, you must match the PPP settings your ISP should have given you.  Some examples are:

Software compression
Encrypted password
Data encryption
IP header compression

If any of these are incorrect or if you user id or password are incorrect, the could cause the connection hangup (NO CARRIER).  If you are not aware of what these settings should be, contact your ISP to get them.

These are actually part of the PPP setup.  What ppp are you using and how did you configure it.

I suspect the problem is in the noauth area.  You might want to look at this question.  It has some 7.3 info at the end:

Also, have you tried using chat to call the isp?

Here is an excellent PPP tutorial I found that may help with your problem.  You might look at the Logging section.  Your logs may give an indication of what might be causing the problem.  Pass on any log information if you need to continue.

Found this tidbit about dropping line connections:

-----
Wrongly configured modem. The first thing the computer does when you ask it to connect via a modem is to send that modem an initialisation string. This is a string of commands that tell the modem how to behave so as to get the optimal performance. Send it the wrong string and life gets frustrating, fast. The string is usually selected when you tell the dialer utility what kind of modem you have. You must select the right configuration file. If there isn't one that exactly matches your modem (the modem should have been supplied with one) you may have to try a few others in the hope of finding something usable.
-----

It could be that minicom is not setting the proper initialization string.  What modem are you using?  Also, I am not familiar with *neat* which you say works properly.  Can you give me some info about *neat*.

If any other experts have any suggestions, please jump in.
