Networking Computers Without Modem?

For the old computers which have no usb nor Ethernet connexion, some very old people amongst us could remember kermit.
kermit is the first free file transfer protocol.
On each computer you defined kermit's adapter (usually it was com2: because com1: was used by the mouse).
On on computer you start kermit in server mode. You simply type "kermit" in a dos box, and at the kermit prompt you type "server".
On the other computer you star kermit, and then you type mget or mput.

Actually, USB to USB between computers is not only possible, it's reasonably fast.

This isn't a free solution, but one piece of software I have been using for more than a decade is FastLynx (not the ISP). Their $50 package includes the two-way USB. If you want to save money, you can get a cheaper package with just serial and parallel cables.

The software is specifically designed for computer-to-computer transfers. One side has a graphical interface that displays navigable directories in both computers, and the other has a slave which does what the other package tells it to do.

Simple, but very effective for file transfers. Especially for older computers that don't have USB connectors.

Full disclosure: I was a beta-tester for the USB version.

USB cannot be Pc to Pc, without a network card and not external storage, all there is is Firewire, which is rare on PCs. Ethernet is pretty common, depends what you mean by lacking modem.

edit: Oh okay, software would get around the 5v power thing which apparantly otherwise can ruin the motherboard.

If you follow these steps to Connect your PCs here I am also clear one thing that what is the use cross and straight cables and which you use for your purpose.
The following diagram shows the Normal use of Crossed and Straight cables
1) <--Straight -->(Hub or Switch) -->Crossed<---(Hub or Switch) <---Straight --->(PC)
2) (PC) <-----Crossed ------>(PC)
Important Notes:
1. We show Straight cables as Bold and Crossed as Italian. cable color can be anything you choose.
2. To avoid the need for Crossed cables if you have UPLINK ports on Hubs or Switches - these are specially designed to allow the use of a straight cable when connecting back-to-back Hubs or Switches.
Crossed Cable Connection:- give the no. of both end same and joined as follows.
One end RJ45 Male Other end RJ45 Male
1 3
2 6
3 1
4 * 5 *
5 * 4 *
6 2
7 * 8 *
8 * 7 *

Straight Cable Connection:- One End Same As other End of RJ45, Color code is Optional if you choose for personal use.
Pin No. conductor color
1 white and orange
2 Orange
3 white and green
4 Blue
5 white and blue
6 Green
7 white and brown
8 Brown
In this way you can physically connected your both PC and if you want to share files use share file system wizard. To share the file.

please dont think that this is perfect way to do this task have so many alternatives so you can use as per convenient.

this is also need.



thanks

You can use a null modem cable so you'll no longer need the RJ11 or the modems.

What you can do is this:

1. Connect your computers using a laplink cable or an RS-232 null modem cable thru your serial ports at the back of your PCs (either DB9 or DB25 connector ports). The cable can be bought from your local computer or electronic stores.

2. Then you can run LapLink software or Windows DCC (Direct Cable Connection) to make the actual system interconnection.

3. Now you can transfer files.



But my suggestion is this:

1. Get a network card for each PC.

2. Connect them thru a crossover UTP cable.

3. Set up each PC to have an IP address of say like 192.168.0.1 and 192.168.0.2.

4. Make them members of the same workgroup.

5. And presto! you got a good fast working LAN!
