PCONS(4) - Device Drivers Manual (sparc64) # PCONS(4) - Device Drivers Manual (sparc64)
NAME # 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 cannot be driven in OpenBSD.
