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.

FILES #

/dev/console

SEE ALSO #

intro(4), tty(4)

HISTORY #

OpenBSD support for the PROM console first appeared in OpenBSD 3.0.

CAVEATS #

If pcons handles console input, the PROM will handle break (or Stop-A) sequences before pcons. The preferred way to enter ddb(4) on a ddb-enabled pcons console is then to enter the following sequence : booksearchexclude = true ‘+++++’
