43 Internal Terminal Emulator graphics driver
48 special files of the form ``ttye?''
51 for bit-mapped displays as implemented under
55 is the main system console on most
58 is the mechanism through which a user communicates with the machine.
59 If more than one display exists on a system,
60 any or all can be used as
62 with the limitation that only the first
63 one opened will have a keyboard (since only one keyboard is supported).
73 However, as currently implemented,
76 does not support the full range of
78 capabilities for this device.
79 Missing are multiple colors, underlining, blinking, softkeys,
80 programmable tabs, scrolling memory and keyboard arrow keys.
81 The keyboard does not have any of the international character
86 It does use the left and right
88 keys as meta keys, in that it will set the eighth bit of the character code.
90 Upon booting, the kernel will first look for an
93 to use as the system console
95 If a display exists at any hardware address, it will be the console.
96 The kernel looks for, in order:
97 a 98544, 98545, or 98547 Topcat display,
98 a 98700 Gatorbox at a supported address (see
100 or a 98720 Renaissance at a supported address (see
102 Currently there is no
105 98548, 98549, 98550 and 98556 boards.
109 (special file opened),
110 all displays go through a standard initialization sequence.
111 The frame buffer is cleared,
114 fonts are unpacked and loaded into off-screen storage and
118 initialization routine also sets the colormap entry used to white.
119 Variable colors are not used, mainly for reasons of simplicity.
120 The font pixels are all set to 0xff and the colormap entry corresponding
121 to all planes is set to R=255, G=255 and B=255.
122 The actual number of planes used to display the characters depends
123 on the hardware installed.
124 Finally, if the keyboard
126 device is not already assigned to another
128 device, it is placed in ``cooked'' mode and assigned to this
132 a display is used both as an
137 and as a graphics device
140 there is some interaction between the two uses that should be noted.
145 that is, write over whatever may be on the
148 When the graphics application is finished and
153 will be reinitialized with the frame buffer cleared
