NAME
pcons - SPARC64 PROM console interface

SYNOPSIS

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 cannot be driven in OpenBSD.
