Hi.
I'm back with another idea.
I investigated a dry pair, and after hours of talking to many people
at the phone company (Verizon), finally someone did give me the
"correct name" of what I was asking for a "PL Dry Pair Circuit". Well
I may still try to get them to do that, but with the trouble so far, I
would like to try another approach first.

Is it possible to connect to a server (with a dotted quad address)
connected via Ethernet to a computer, by setting up that computer to
answer a dial-up call (via 56k modem) from a computer calling it. That
is dialing the computer directly, not through the Internet.

I understand that I can set up the "host" computer to answer an
incoming call, but how do I then get the connection to another server
through that connection?

Thanks so much for your help,

Harvey

I believe you mentioned MS Windows. If so, then the ability to reach
other systems should be on by default when you use SLIP (that I
mentioned before) or (the bettter, more complete) setup instructions
that someone posted in response to that -- usually you have to
specifically turn it off!

Microsoft mostly calls this "Internet Connection Sharing" (ICS).
The name that security people call it is not printable in
polite company ;-(

To turn it on, run the Network Setup Wizard and choose the
first option "This computer connects directly to the Internet.
The other computers on my network connect to the Internet
through this computer.

You may also be able to put something into effect by selecting
the Network Connections portion of the Settings area, and on the
resulting page, bring up the properties on the local area network
and fiddle through there a bit to find Connection Bridging. I haven't
checked to see if that is the same as ICS.

SLIP and PPP allow IP connections through serial links.
Most likely you can't get higher than 33.6K, though. A 56K modem
requires an ISDN or T1 at the other (answer) end.

It isn't so hard to find hardware that will do SLIP or PPP now.

Some years ago I did it with PCroute. It was running on
a 10MHz 8088, barely fast enough to keep up with a 9600 baud
link. No login, just connect an answer modem on one end,
and an originate on the other. I kept the line up all the
time, static IP addresses (even RIP running through it).
I had PCRoute machines running at both ends, connecting
to ethernet at home and office. That was before the
web became popular, though at the end some web
pages went through it.

Easiest is to do static IP address and static default route.

are we still talking about the camera setup ??
or is this a different "question" ??

BTW - why have an "extra" computer just for the dialup?
There are different ways to put the modem directly on your "server",
and dial into it.
Most solutions are a "remote control" or "remote desktop".
In other words, after you connect,
you are sitting at the "remote" desktop.

What do you want to do after you have connected ??

It is for monitoring 5 cameras. The camera setup is in place and
working over the internet using dial up, but it is too slow. The
picture updates only about every 5 to 40 seconds. I assume that
internet traffic is the variable. Once every two seconds or faster
would be good.

What do you recommend for wireless through a fairly wooded area?


And again can the phone company provide a connection in the existing
buried wiring? They always have extra pairs available, right? Both
locations are on the same dead end road.

Is there such a thing as an external 56k modem that connects to a
computer (or LAN) via Ethernet?

Yes, still the camera setup. Forgive me for bouncing around with a new
thread.

Well, I need more information. I just spent several hours at the
installation site where I have two phone lines to work with (only one
at home) and I couldn't get anything to work. I wish I could try this
at home.

The "server" is not a "computer", it is a camera scanner box. I don't
know anything about causing it to know about answering a dial up
modem. Thus the "extra" computer. So I guess the "extra" computer that
will answer the dial up call will be the "server" that gives access to
the camera scanner via Ethernet.

As it is currently set up the camera scanner box connects directly to
a Hughes-Net modem. No other computer is involved on that end. Anyone
having the dotted quad IP address of the scanner can monitor the
cameras via the internet.

Any more insight will be greatly appreciated.

Yes, Win XP. Do I select SLIP on the calling end, the answering end or
both.

Yes. There are versions that provide virtual serial ports
(but those usually require a driver on the system they are providing
the port to), and there are dial-up servers that provide the dial-up
user with an IP connection to a remote network; these usually use
PPP or SLIP.

OK, assuming that I have no control over the camera scanner box (I
don't know much about it), can I access it from a dial up computer
(Win XP) using such a modem (V92, Ethernet)?
Please give me some examples of these modems (make and model). Are
they expensive?
Thanks,
Harvey

we keep getting little bits and pieces of the puzzle,
all of which is needed to offer any useful advice.

You say it is working over the Internet using dialup,
but it is too slow
What is too slow ??????

Are you viewing photos from these 5 cameras ??
How big are the images ?
If they are 2meg each and you are dragging 5x worth,
well - that's your problem !!! 10meg of data across a dialup connection !!

In other words - let's get ALL the facts so we know what's going on
What is the photo scanner box - is there a model, website, etc ?
How is it currently being using ??
How does it connect to the Internet ?? via a dialup modem ??
How do you connect to it ?? and what software do you use ?
Do you just view the images, or are you downloading them for later viewing ?

It's like asking "what kind of tires should I buy" ??? without the
details -
car, truck, motorcycle, bicycle, etc

ALL of these elements impact any kind of response....
SO - the more you explain exactly what you have, what is working,
and why you need to "go faster" - then we will all understand -
