NAME
     utserial, utparallel - Sun Ray serial and parallel port dev-
     ice driver emulators

SYNOPSIS
     #include <sys/types.h>

     #include <fcntl.h>

  utserial
     #include <sys/termios.h>

     #include <termio.h>

  utparallel
     #include <sys/ecppio.h>

DESCRIPTION
     utserial is a tty-style interface that  provides  a  generic
     virtual  interface  to  USB serial adaptors connected to Sun
     Ray appliances.

     utparallel is a parallel-style  interface  that  provides  a
     generic virtual interface to USB parallel adaptors connected
     to Sun Ray appliances.

     utserial and utparallel are each loadable STREAMS drivers.

     The actual interface to the  appliance  for  each  of  these
     drivers  is  by  network  interconnect  through  either  the
     utseriald daemon or the utparalleld daemon, each of which is
     session-aware.  The daemons are connected to either utserial
     or utparallel through a master port, and each is responsible
     for  creating  the  slave  device nodes through which normal
     applications will connect.

APPLICATION PROGRAM INTERFACE
     Applications open a device file created by either  utseriald
     or  utparalleld. Device files created by utseriald comply to
     the  termio(7I)  interface,  and  device  files  created  by
     utparalleld comply to the ecpp(7D) interface. Hardware limi-
     tations in USB adaptors might prevent compliance with  these
     interfaces.

FILES
     The following files are used:

          /dev/utserial
                Master port for utserial

          /dev/utparallel
                Master port for utparallel
