ITE(4)               NetBSD/amiga Kernel Interfaces Manual              ITE(4)


NAME

     ite -- Amiga Internal Terminal Emulator


SYNOPSIS

     ite0 at grf0
     ite1 at grf1
     ite2 at grf2
     ite3 at grf3
     ite4 at grf4
     ite5 at grf5
     ite6 at grf6
     ite7 at grf7


DESCRIPTION

     TTY special files of the form ``ttye?''  are interfaces to the Amiga ITE
     for bit-mapped displays.  An ite is the main system console on most 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 sys-
     tem, any or all can be used as ite 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.

     ite devices use the HP-UX `300h' termcap(5) entry.  However, as currently
     implemented, the ite does not support the full range of HP-UX capabili-
     ties for this device.  Missing are multiple colors, blinking, softkeys,
     programmable tabs, scrolling memory and keyboard arrow keys.  The key-
     board will use the left and right Amiga keys as meta keys, in that it
     will set the eighth bit of the character code.  ite devices also do a
     good job at emulating the `vt100' termcap(5) entry.

     Upon booting, the kernel will first look for an ite device to use as the
     system console (/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 highest-numbered one).

     On most systems, a display is used both as an ite (/dev/ttye? aka
     /dev/console) and as a graphics device (/dev/grf?).  In this environment,
     there is some interaction between the two uses that should be noted.  For
     example, opening /dev/grf0 will deactivate the ite that is, write over
     whatever may be on the ite display.  When the graphics application is
     finished and /dev/grf0 closed, the ite will be reinitialized with the
     frame buffer cleared and the old colormap installed.
