This was a simple approach that worked back when there were few network adapters, but you can see a few problems with it. So if I understand, we must use the 3c The time now is Decoupling the network hardware programming from the applications made the applications smaller and less complex while allowing them to handle new adapters with no changes, provided that the new adapters provided a packet driver. But does it really work, the drivers loaded and configured for sure, but i can not reach the router. On a modern operating system networking is a standard function and great effort has been made to make it easy to setup.

So you can use it, but you will have to live with any bugs and limitations. All Ethernet cards have unique addresses, assigned by a central entity. Join Date May Posts 5, There are lots of factors that go into choosing networking hardware.

Feeling lucky, is the 3cB compatible with using NE drivers? Pxcket for DOS is always an add-on feature so it takes a little bit of work to set up, but nothing too difficult.

This is usually in lieu of transferring the information over a computer network. The approach that you choose will probably be driven by the applications that you want to use.

Protocol suites are interesting but most people do not interact with them; they use applications that hide the details of the protocol suite and underlying data transfer medium.

Another way to look at it is that your networking software never really talks directly to the networking hardware. If you are running DOS on such a high powered machine, I applaud you.

This probably been discussed many times, the 3cB will work in a 8-bit ISA slot however the driver require There are lots of ways to connect computers together. I would look for a adapter from a well-known manufacturer with an RJ45 connector and a good packet driver.

DOS TCP/IP Networking with Packet Drivers

Here is my set of criteria:. If people had any sort of connectivity it might have been to use a bulletin board system BBS through a dial-up modem or to talk to a Novell Netware server running on their local network.

Even packte slowest DOS machines dating back to the early s can do the following once networked:. Originally Posted by JT Last Jump to page: In that case it could probably be modified to work by someone more knowledgeable on x86 assembly than me! Parallel ports ;acket evolved to operate at faster and faster speeds using improved handshaking on the wires packey even DMA. Being realistic, you are not going to want to use DOS to surf the web.

One of the great things about NCSA Telnet is that the source code is readily available for download – with the correct build environment, you can modify it!


This page barely scratches the surface of DOS networking. They switched to a packet driver interface when the variety of Ethernet cards mushroomed.

C3509b see that the driver has different input routines for and Those enhancements were made to improve the speeds of connected devices, but they would help data transfer of any type. That hardware might be a network adapter, an Ethernet chipset connected through the parallel port, or even just a plain serial port. Modern web sites are generally too complex to render on old machines and the extensive use of Javascript has made it difficult for old machines.

3Com Software Library – Network Interface Cards

The software allowed the computers to move files back and forth. A full implementation requires more memory than is usually available on an old PC. Application software would use the API to send and receive packets.

But performance is not as good as with the first approach and the “one size fits all” philosophy leads to some design compromises that may not be good for the individual programs. The packet driver makes itself available to higher level software by taking control of a software interrupt.

Stated requirements are DOS 2.
