60 is the main system console on most
63 is the mechanism through which a user communicates with the machine.
64 If more than one of the supported displays exists on a system,
65 any or all can be used as
68 with the limitation that only
69 one will have a keyboard (since only one keyboard is supported) and only
70 one of each type can be used.
78 However, as currently implemented,
81 does not support the full range of
83 capabilities for this device.
84 Missing are multiple colors, blinking, softkeys,
85 programmable tabs, scrolling memory and keyboard arrow keys.
86 The keyboard will use the left and right
88 keys as meta keys, in that it will set the eighth bit of the character code.
90 devices also do a good job at emulating the
95 Upon booting, the kernel will first look for an
98 to use as the system console
100 If a display exists at any hardware address, it will be the console.
101 The kernel looks for them in decreasing order (that is, choosing the
102 highest-numbered one).
105 a display is used both as an
110 and as a graphics device
113 there is some interaction between the two uses that should be noted.
