Jumpers for Practical Peripherals Modems

The modem that you received with your Practical Internet Kit, uses jumpers to set the COM port and IRQ. Both a COM port and an IRQ must be selected for the modem to operate correctly.

A jumper is a small piece of plastic that will fit down over two copper colored wires. The pair of copper wires is called the header. When the jumper is covering the header, that is usually described as being 'JUMPERED'. In the case of your modem, when E1 alone is 'JUMPERED', your modem is setup for COM 3.

You will find the jumpers for your modem located near where your modem would plug into the slot on your PC. These area will look like several copper colored stripes running from the edge of the modem card. The jumpers are about ½ " from the edge of the board.

The following is a listing of the possible selections for your modem. Your modem supports COM 1 through 4 and IRQ's 2 through 5. You can configure your modem to be any combination of these settings.

This is an example of how the jumpers on your modem would look if your wanted it configured for COM 3 IRQ 5. Notice that no other jumpers are present other then those that you need to set the COM port and the IRQ. You must select both a COM port and an interrupt. No other device on your system can use the same interrupt and/or COM port as your modem. If something else is using one of these, you will have a conflict and your modem will not function correctly.

Other Internal Models

The older internal models that supported IRQ selection had a DIP switch on the back of the card for COM port selection and a set of jumpers that are used to configure the IRQ setting.

The DIP switch on the back of the modem is used to configure the modem for COM1 through COM4. IRQ's can be selected using the jumpers.

Here is an example of how to configure this style of modem for a COM port and IRQ setting.

Newer internal models setup both the COM port and IRQ selections through a series of jumpers on the card.

The jumpers are used to configure both the COM port and IRQ settings.
