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.
