Latency issues can be reduced by complex programming called client side prediction, but it will not fade until cheap, high speed, digital Internet access is available to the majority of consumers. When that occurs, Internet multi-player gaming will be the only way to go. With advancements in consumer Internet access around the corner and computer hardware like 3D Accelerators we are on the verge of being able to create a true interactive virtual society. One of the most primitive ways is through direct connection. To make this possible, two or more computers are connected through their serial ports with a null-modem cable.
Some games allow multiple players to connect to the same game through a modem connection.
To create a modem connection, the two players should select a modem as their connection type. Then the game should automatically answer the incoming call and establish a connection. A disadvantage to this type of connection is only two players can engage in the game. Another type of connection that usually allows for four or more player, depending on the game, is an IPX network connection. Here, all the computers that want to engage in the game should be connected to an IPX-compatible network.
