ezScan (ver 3.31) Abandoned Freeware ezScan is an on-screen scanning keyboard TSR that can be operated from a single or dual switch attached to the game or serial port. A highlight bar moves down the on-screen keyboard first by row and, after the switch is pressed, by column. By pressing the switch again, the user can make selections which correspond to each of the keys on a computer keyboard. If you have a joystick already connected to the computers gameport, you can easily see how the program works by launching the TSR with the parameters: EZSCAN /G then, at the DOS prompt, pushing the "trigger" button on the joystick.
