The first following byte's high bit represents the state of the left button. The lower seven bits represent the x-axis acceleration. The lower seven bits of the second byte represent y-axis acceleration. 0x3f The x server interprets this keycode as a middle button release. 0xbf The x server interprets this keycode as a middle button depress. 0x40 The x server interprets this keycode as a right button release. 0xc0 The x server interprets this keycode as a right button depress. NOTES: There should be a better way of handling mice in the X server. The MOUSE_ESCAPE code (0x7e) should be followed by three bytes instead of two. The three mouse buttons should then, in the X server, be read as the high-bits of all three bytes. The x and y motions can still be in the first two bytes.
