NAME
       usoc - universal serial optical controller for Fibre Channel arbitrated
       loop (SOC+) device driver

DESCRIPTION
       The Fibre Channel adapter is an SBus  card  that	 implements  two  full
       duplex  Fibre Channel interfaces. Each interface can connect to a Fibre
       Channel arbitrated loop (FC-AL). The usoc  device  driver  is  a	 nexus
       driver and implements portions of the FC-2 and FC-4 layers of FC-AL.
