For this system to work you need to tell the packet driver what software interrupt it should claim. A full implementation requires more memory than is usually available on an old PC. Transfers on the parallel port were inherently faster than those over serial ports because of the nature of the parallel port. This drove the cost of networking adapters and equipment down, which made it more affordable for home users. It assumes a specific data transfer port number, which is what was standard years ago. I did not see any activity on LEDs.

For this system to work you need to tell the packet driver what software interrupt it should claim. Even in other XT clones. A real IRQ allocation test would require hooking up to all hardware interrupts, somehow making the device to generate an interrupt, and checking what interrupt got triggered. Brutman, mbbrutman at gmail. Serial ports supported “hot plugging” removing and connecting devices while running while parallel ports did not, so swapping devices on a parallel port often required shutting the computer and the devices off.

A “software service” for sending and receiving raw Ethernet packets is in place, courtesy of the packet driver. Here are some places to look for a packet driver for a specific Ethernet device.

The approach that you choose will probably be driven by the applications that you want to use. A packet driver makes the hardware dod network accessible in an easy manner. Now i look for an older card. You also need to tell the other software what software interrupt that the packet driver is listening too.

The card gets initialized, but not a single bit is transmitted.

Unfortunately the web pages for Trumpet are gone now. After the packet driver is installed, other software will use the packet driver by setting parameters and issuing the software interrupt.

Serial ports are relatively easy devices to program and lots of people wrote software that uses the serial port.

I tried to load NE packet driver and ping. Here are some examples:. Those 3c509bb were made to improve the speeds of connected devices, but they would help data transfer of any type.

Here is my set of criteria:.

Last card I will have I do not have yet is this card. For 16 bit ISA bus machines you can use nearly anything.

As a result, there was a great variety of programs that used different rules for sending data. Return to General Old Hardware. Most of my experience has been with packet drivers and related software; a list of additional resources is provided to help you understand packet driver based solutions and other solutions that I mentioned earlier.

So you can use it, but you will have to live with any bugs and limitations. A notable exception was LapLink xos Traveling Software. Yes the one that I used for tests.

Parallel ports also evolved to operate at faster and faster speeds using improved handshaking on the wires and even DMA. You can find the files here: I would have never looked in UNIX archive. At the beginning of the networking era for DOS PCs there were very few network adapters to choose from and network applications were highly specialized. Behind the 4 pin molex connector on the first picture above, in my original post. When the packet driver loads it is going to look for the Ethernet adapter and try to communicate with it to ensure that the Ethernet adapter is available.

An 8-bit Western Digital WD Ethernet card from is very different from a NE clone in a PC, yet the packet drivers for each card make them look the same to the rest of the system. The name is a tongue-in-cheek sound-alike to Ethernet, and refers to the use of someone wearing sneakers as the transport mechanism for the data.

The software interrupt to use is usually specified on the command line when the packet driver is loaded. Note that some newer cards didn’t have jumper headers soldered or even didn’t have a place for them on the PCB.
