How to Hook Computers Together With Cables

The most common way to connect two computers is by using a Null Modem Cable. Once computers are linked, information and data can be readily transferred.

Step 1 Purchase a Null Modem Cable (see Resources below). Beforehand, measure the distance between the computers you are linking so that you buy the proper length of cable.

Step 2 Connect the cable to the serial ports on the back of each computer.

Step 3 Choose which computer will be the "host" computer and which computer will be the "guest."

Step 4 Open the Control Panel on the host computer. Select the "Network Connections" tab and choose to create a new connection. Choose to set up an advanced connection and then choose the option for connecting your computer directly to another computer.

Step 5 Select the connection device for your computers from the list of options and allow access for the guest computer. Select "Finish" when you are done.

Step 6 Open the Control Panel on the guest computer. Select the "Network Connections" tab and choose a name to identify this computer connection. Select the connection device for your computers from the list of options. Decide whether all users of the computer will be able to use the connection or whether you will limit it to certain users. Select "Finish" when you are done.
