Find the Dnet package.  Install it on yuor unix system.  Install it on your
amiga.  I found it impracticable with a 2400 baud modem, but at 9600 it is
usable.

In essence it provides a multi-session connection to a unix account in true
amiga style.

Did you install the new Aux-Handler, Port-Handler and Mount command?

Welcome to the club.  Thankfully you only need it to set the default

   i was hoping to be able to use a dumb terminal with my

   all i can do is use terminal programs (by the way they work ok)
   like ncomm and handshake and select any port i want. needless
   to say i am dissapointed in paying what i did for it and it
   doesn't work.

   any ideas?

See above.  You can do what you want to do if you install all the
software correctly.

When you log out of a VAX it sends the final message, then drops the DTR
signal to tell the modem to hang up. If the modem has some buffering
in it, which most faster ones do, the message may still be in the buffer, and
only partially sent, at the point where the DTR line drops, and the modem
hardware releases the phone line (thus the NO CARRIER).

Some modems may be programmable to delay the hangup for a short period after
losing DTR, to avoid that, but you'd need to take it up with the admin 
staff at the BBS or University. There isn't anything you can do at your
end.

Thanks to all who responded about this problem, in particular James 
Franklin (jf@debi.uoknor.edu) who was kind kind enough to mail me the full 
archive.  
It was a silly problem with my brain that caused all the problems.  On my 1.3 
A1000 I didn't need to set the stack before running AtomClock.  Not bothering 
to read the docs (it always worked before!) I ran it on the Tower without 
adjusting the stack.  Crash.
All is well now (and on time even).

	Thank you for the wonderful comment.  Gee I guess this is my first
flame...  Feels great.  :-)  First of all you semi-evolved-semian JR-Comm
has it because he ASKED for permission to include it in his software.
Second of all, I don't believe that ANSI is copyrighted.  It is a

worth using, was because some IDIOT stole the Skypix (c) protocol and put
it into C-NET without permission.  In DIRECT violation of copyrights.

	Uh, Thad... YModem or ZModem will neither of them allow him to maintain
and interactive session with his account while the transfer is going on. :-( DNet
and SLIP are the two easiest to implement that I know of.

Well, do you have anything in the side port of the 500?  I just recently  
saw a "single 2000 compatible slot" for the 500, which basically looked  
just like a gender changer that fits in the side of the 500 and allows you  
to use any 2000 cards.  I asked my dealer about plugging in an Ethernet  
card (since we're getting net connections in the rooms as well), and he  
said that it would work...

And it works marvelously (when carriers get their act together).  We use it
to connect radio studios all over the country at my network.  We use the
mono 7K system, but will soon use the stereo 15K setup soon.  It works and

Arrgh!

As someone kindly pointed out, the guy wanted to continue an interactive
session with the UNIX box, not with the Amiga console.

As many who've used Amigas since Day 1 can attest, some comm programs have
NOT been system-friendly and have taken-over the machine.

So, as I try to weasel-out of this gaffe (:-), lemme say there IS a way to do
what the original requester wanted, using uwindows and Meshugena.

He doesn't do kermit.  In fact, he sent a person to ME to explain how to get

I have used Enlan for a couple of years now, and it is indeed available and works
