NAME    [Toc]    [Back]

     pcons - SPARC64 PROM console interface

SYNOPSIS    [Toc]    [Back]

     pcons0 at mainbus0

DESCRIPTION    [Toc]    [Back]

     The pcons device provides a simple text console,  using  the
PROM services
     for  input and output.  It will use the PROM console devices
set via the
     ``input-device'' and ``output-device'' variables.

     This driver is deprecated and only provided  as  a  fallback
console mechanism
  if  the  real  console  hardware  can not be driven in

HISTORY    [Toc]    [Back]

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

CAVEATS    [Toc]    [Back]

     preferred way to enter ddb(4) on a ddb-enabled pcons console
is to enter
     the following sequence : `+++++'
