** Mouse driver 0.0.3
|
||||
** Written by Jason Filby (jasonfilby@yahoo.com)
|
||||
** For ReactOS (www.sid-dis.com/reactos)
|
||||
|
||||
** Note: The serial.o driver must be loaded before loading this driver
|
||||
|
||||
** Known Limitations:
|
||||
** Only supports mice on COM port 1
|
||||
|
||||
** Old Driver, We done build it. Just keep for History. (S.E.)
