pcons - SPARC64 PROM console interface
SYNOPSIS
pcons0 at mainbus0
wsdisplay* at pcons?
DESCRIPTION
The pcons device provides a simple text console, using the PROM services
for input and/or output if no other driver handles this task. It will
use the PROM console devices set via the ``input-device'' and
``output-device'' variables.
This driver is provided as a fallback console mechanism if the real
console hardware can not be driven in OpenBSD.

enabled pcons console is then to enter the following sequence : `+++++'
