Line 371:
All PS/2 devices should support the "reset" command (which is a command for the device, and not a command for the PS/2 Controller). To send the reset, just send the byte 0xFF to each (usable) device. The device/s will respond with 0xFA (success) or 0xFC (failure), or won't respond at all (no device present). If your code supports "hot-plug PS/2 devices" (see later), then you can assume each device is "not present" and let the hot-plug code figure out that the device is present if/when 0xFA or 0xFC is received on a PS/2 port.
'''TODO''': Potential wiki error, the 0xFF reset device command seems to respond 0xAA and then 0xFA on self-test success, and [[PS/2_Keyboard]] agrees. --[[User:Sortie|Sortie]] 14:15, 27 April 2015 (CDT)
