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.
EXAMPLES
If you want to run getty(8) on dcons, insert the following line into /etc/ttys(5) and send a HUP signal to init(8) using kill(1). dcons "/usr/libexec/getty std.9600" vt100 on secure Once the fwochi(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.
FILES
