NAME
     onewire - 1-Wire bus

SYNOPSIS

     onewire* at ioc?	    (sgi)
     onewire* at xheart?    (sgi)

     option ONEWIREVERBOSE

DESCRIPTION
     1-Wire bus was originally developed by Dallas Semiconductor for
     connecting integrated circuits.  It is commonly used for connecting
     devices such as electronic keys, EEPROMs, temperature sensors, real-time
     clocks, security chips, etc.

     The onewire driver provides a uniform programming interface layer between
     1-Wire master controllers and various 1-Wire slave devices.  Each 1-Wire
     master controller attaches a onewire framework; several slave devices can
     then be attached to the onewire bus.

     The driver supports plugging and unplugging slave devices on the fly.
