Manufacturer/Support Electronic Arts, Inc. Battle Chess for DOS: DIP Switches 3,5, and 8 DOWN(ON) This chess game allows you to play against an opponent, modem to modem. We have found that using the init string "AT&F&M0&N1" at 300 baud works fine. If you would like to connect at a higher speed, try setting the init string to "AT&F1". Due to the nature of the game, speeds higher than 300 baud are not necessary.
