User arbitration
Control of the host computer is arbitrated by the module on a first come, first served basis. At the moment that a key is pressed or a mouse is moved by a user, the keyboard and mouse of the other user are temporarily locked-out (the video images remain). The keyboard indicators of the locked-out user then begin to flash to confirm their status. After two seconds of inactivity from the user currently in control, the module returns to its idle condition and re-instates the keyboard indicators of the locked-out user.
