DCONS(4)		 BSD Kernel Interfaces Manual		      DCONS(4)

NAME
     dcons — dumb console device driver

SYNOPSIS
     device dcons

     options DDB
     options ALT_BREAK_TO_DEBUGGER

     device firewire

DESCRIPTION
     The dcons device is a simple console device which just reads from and
     writes to an allocated buffer for input and output respectively.  It is
     of no use by itself and it is supposed that the buffer is accessed via a
     bus like firewire(4) or kvm(3) for interaction.

     The buffer consists of 4 channels.	 There are 2 ports, one for the con‐
     sole TTY and another is GDB port, then each port has an input channel and
     an output channel.

FILES
     /dev/dcons
     /etc/ttys

EXAMPLES
     If you want to run getty(8) on dcons, insert the following line into
     /etc/ttys and send a HUP signal to init(8) using kill(1).

	   dcons   "/usr/libexec/getty std.9600"   vt100   on  secure

     Once the fwohci(4) device is initialized to allow physical access, the
     buffer can be accessed from another host via a firewire(4) bus using the
     dconschat(8) application.	See dconschat(8) for more details.
