# 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 : ‘+++++’
