Serial networking

I've been at this before, but thought I'd have another go at it since I've acquired a reasonably small 800Mhz PC with a wireless NIC:

I'd like to network my Amiga to the PC via the serial port, thus making use of the PCs internet-connection (AmigaOS3.9 > null modem cable > WinXP > Internet). Now, I know this is possible. I just don't know how

In short: 1.How do I configure MiamiDX to achieve this?
2.How do I configure WinXP to allow this?

Anyone?

I have done this and can say to you don't want to bother, REALLY!!!

It's too slow. Go parallel or TCP/IP.

Serial/SLIP etc has a transfer rate slower than your floppy drive access.

If you get a mirror and sit and stare into it you can actually physically see yourself age, it takes that long to transfer data.

I even took the £15 Null modem cable BACK to the shop and got a refund it was that slow.

My advice, have a sniff about on Ebay for a 3com 3c589 /b/c/d/combo card with dongle for a couple of quid. Use a modded patch cable or treat yourself to a crossover cable. Or if you're really posh, buy a little hub.

And, jobs a good 'un.

However, if you do decide to continue:

Useful links in your quest:

Robs Amiga Transferring Tips:

Slip Protocal Guide (Aminet.net)

Wiki:
http://en.wikipedia.org/wiki/Direct_cable_connection


Some things to remember:

Null Modem Cable.
Comms Port Properties: Bits per second, Data bits, Parity,Stop Bit Flow control, FiFO Buffers,

I've just remembered aswell, you'll need some software on WinXP to open the serial com port layer, as WinXP does not talk directly to the com ports for security reasons. There is some stuff on sourceforge.net but try this option first http://www.freedownloadscenter.com/B...nxp-ports.html

Can't remember the names, x2 types of software I'm thinking of, god my brain hurts. Rahhhhh!

Though your easiest option is to install Amiga Forever's software as this will hard-wire a protocal for connecting you directly to Amiga/WinXP. Use Miami SLIP protocal on Amiga, don't forget to configure the COM port settings.

You the Man. Do IT!

Depending on what you intend to use the Shared Internet Connection from Windows XP for. Bare in mind the "serial connection speed" / "transfer data speed" you are using.

Therefore making allowances for this in your selection of applications on the Amiga. Simple Telnet, FTP, Pine, Alynx (think Unix Terminal)

In other words, there is no point hammering seven bells of hay out of your internet connection with big beefy applications, because your internet connection will bottle necked.

Remember: You ARE the Man..

ive tried multidace and ioblix serial cards (upto 0.5mbit) and in pc was fast serial port card (dont remember the brand, Kouwell probably).
it works great thru tcp, even A2000 (020) can do around 30kB/s which is sure enough for jabber or e-mail. but it has one big flaw all guides (aminet etc) are wrong - pc acts as "dialer" so after it connects to amiga it drops internet connection. bah
if anybody solve it other way ( amiga acts as dialer and on pci will be installed some proxy sw) let me know. i have bunch of multiface and ioblix cards. I will give one multiface3 to that man!

Yes. It is most definitely slow. The Amiga's serial port being the main bottleneck as far as I can understand. But I'm aware of that. I just want it connected so that I can use IRC and some other, less demanding applications. Eventually, I will hopefully find myself a Zorro-NIC at a reasonable price, and connect directly to the router. But, having a suitable nullmodem-cable and a small PC (the size of a laptop without the monitor) with a spare wireless NIC, I thought this to be a reasonable solution for the time being. I will look further into the matter. Many thanks for your suggestions.

Happy RS232 RJ45 Adaptor

You might wish to read this article to:

http://www.lammertbies.nl/comm/cable...rial-rj45.html

I would be interested to see if this could be achieved with an Amiga.

Certainly using an old PC configured to auto-boot and connect to the internet and allow sharing via the serial port is an option.

That IS very interesting. Should I ever decide to put my soldering skills (or rather lack of such) to the test, this is the project

Hooooo Mummy

Some more MEGA information:

http://www.taltech.com/products/tcpcom.html

The problem using this method is hindered by the lack of software support for the amiga to utilise these Unix techniques.

You'd need DCE RS232->RJ45 (I have these connectors in the loft)

I want someone to PROVE me wrong and get this concept to work. COME ON! PROVE me WRONG damn YOU!

Because I want to try it out.

Swedish Girls.. Hmmm nice!

I think the quickest and simplest option is to:

1. Buy a null modem cable
2. Install Amiga Explorer configured to serial link (Amiga)
3. Install Amiga Explorer configured to TCP/IP mode (Windows)
4. Install a FREE Proxy Server application on Windows.

For the computers to use TCP/IP over a null-modem serial cable, the appropriate SLIP (serial line IP) drivers and options must be set both on the PC (see the Windows documentation, as SLIP is part of the system) and on the Amiga (see the Amiga TCP/IP documentation).

I did this but with a Linux setup in my PC.
I set up a SLIP connection to my Amiga and it worked OK using Miami.
But as soon as I transferred some stuff I chose some other option like TwinExpress...
It should be good for IRC though, I remember telnetting into somewhere...

You wouldn't happen to still have the configuration-file for Miami, would you?

I would have to look in my A600, which I have 1000s of km. away.
Sorry ;(

And who was it that once said that the A600 wouldn't go far?

Hahahha.
Actually she staid there and I travelled ;D

What exactly is your problem with this? Have you got the PC side set? I could give you a hand off the top of my head with configuring Miami , maybe.

No. I do believe the PC-side will be the major challenge. At least using WinXP. I can't be certain MiamiDX is properly configured though, since the PC most certainly isn't. So if I could get hold of a working configuration at either end, I would have something to work with. As it is now MiamiDX "goes online" and provides itself with a local IP which I - obviously - can ping locally, but not from the PC. Hence my somewhat blunt request for a configuration-file..

If you're willing to look into to the matter though, I would happily send you the latest configuration-file I've used. But you'd have to promise to be gentle..
