.Sh DESCRIPTION
|
|
.Tn TTY
|
|
special files of the form ``ttye?''
|
|
are interfaces to the
|
|
.Tn Amiga ITE
|
|
for bit-mapped displays.
|
|
An
|
|
.Nm
|
|
is the main system console on most
|
|
.Tn Amiga
|
|
workstations and
|
|
is the mechanism through which a user communicates with the machine.
|
|
If more than one of the supported displays exists on a system,
|
|
any or all can be used as
|
|
.Nm
|
|
.Ns s
|
|
with the limitation that only
|
|
one will have a keyboard (since only one keyboard is supported) and only
|
|
one of each type can be used.
|
|
.Pp
|
|
.Nm Ite
|
|
devices use the
|
|
.Tn HP-UX
|
|
.Sq Li 300h
|
|
.Xr termcap 5
|
|
entry.
|
|
However, as currently implemented,
|
|
the
|
|
.Nm ite
|
|
does not support the full range of
|
|
.Tn HP-UX
|
|
capabilities for this device.
|
|
Missing are multiple colors, blinking, softkeys,
|
|
programmable tabs, scrolling memory and keyboard arrow keys.
|
|
The keyboard will use the left and right
|
|
.Tn Em Amiga
|
|
keys as meta keys, in that it will set the eighth bit of the character code.
|
|
.Nm Ite
|
|
devices also do a good job at emulating the
|
|
.Sq Li vt100
|
|
.Xr termcap 5
|
|
entry.
|
|
.Pp
|
|
Upon booting, the kernel will first look for an
|
|
.Nm ite
|
|
device
|
|
to use as the system console
|
|
.Pq Pa /dev/console .
|
|
If a display exists at any hardware address, it will be the console.
|
|
The kernel looks for them in decreasing order (that is, choosing the
|
|
hightest-numbered one).
|
|
.Pp
|
|
On most systems,
|
|
a display is used both as an
|
|
.Nm ite
|
|
.Pf ( Pa /dev/ttye?
|
|
aka
|
|
.Pa /dev/console )
|
|
and as a graphics device
|
|
.Pq /dev/grf? .
|
|
In this environment,
|
|
there is some interaction between the two uses that should be noted.
|
|
For example, opening
|
|
.Pa /dev/grf0
|
|
will deactivate the
|
|
.Nm
|
|
that is, write over whatever may be on the
|
|
.Nm
|
|
display.
|
|
When the graphics application is finished and
|
|
.Pa /dev/grf0
|
|
closed,
|
|
the
|
|
.Nm
|
|
will be reinitialized with the frame buffer cleared
|
|
and the
|
|
old colormap installed.
