NAME
     utseriald - Sun Ray enterprise serial service daemon

SYNOPSIS
     /opt/SUNWut/bin/utseriald [ -D debug-level ]  [ -o optroot ]
     [ -r ]

DESCRIPTION
     utseriald provides serial support for  Sun  Ray  appliances.
     utseriald  supplies driver services for USB serial adaptors.
     For  a  list  of  supported  adaptors,  see  the  web  site:
     http://www.sun.com/sunray.

     utseriald uses the utserial(7D) loopback driver  to  provide
     Solaris  applications  the  same  interface for serial ports
     connected to a Sun Ray  appliance  as  standard  workstation
     ports,  such as /dev/term/a or /dev/term/b. Solaris applica-
     tions such as tip(1) can change port settings by  using  the
     standard termio(7I) interface.

     When an application opens a device node, the ldterm(7M)  and
     ttcompat(7M) modules are pushed below the STREAM head.

     utseriald enables standard Solaris serial services using the
     utserial(7D)  loopback  driver.  When  a  serial  adaptor is
     attached to an appliance, utseriald creates device nodes  in
     the  /tmp/SUNWut/units/tid  directory  (tid  = terminal id).
     UTDEVROOT points to this directory through a symbolic  link.
     A  user  can use $UTDEVROOT/dev/term/terminal-name to access
     the serial ports on the Sun Ray appliance.

     Error messages from utseriald are  logged  using  syslog(3),
     with a facility value of LOG_DAEMON.

OPTIONS
     The following options are supported:

     -D debug-level
           Debug mode. Use is beyond the scope of this document.

     -o optroot
           Use optroot for the serial  service's  root  directory
           for   device  node  creation.  The  default  value  is
           /tmp/SUNWut. optroot should be the same  directory  as
           the optroot directory used by utdevmgrd(1M).

     -r    Automatically restart the serial service daemon if  it
           exits.  With  this  option,  the serial service daemon
           creates two processes: a child that performs  all  the
           actual  work,  and  a  parent  monitoring process. The
           parent process restarts a child if  the  previous  one
           exits.

ENVIRONMENT VARIABLES
     UTDEVROOT is a variable that points to a  symbolic  link  to
     the  device root for the Sun Ray appliance associated with a
     user's session.

FILES
     The following files are used:

     /tmp/SUNWut
           The customary location for temporary files used by Sun
           Ray enterprise server managers, designated by optroot.

     /tmp/SUNWut/.utdevmgr
           The named pipe used for communication between the dev-
           ice manager and device driver services.

     /tmp/SUNWut/units
           The directory containing device directories  for  each
           appliance.  The directories are named after the appli-
           ances' serial numbers. Each directory contains  a  dev
           directory and a devices directory.

     /tmp/SUNWut/units/tid/dev/term
           The directory containing links to serial device  names
           for  each  appliance. tid is the unique terminal iden-
           tifier for an appliance.

     /tmp/SUNWut/sessions
           The directory containing links to  appliances  in  the
           units directory, named by X-Windows display number for
           each session. These links change as  users  move  from
           one Sun Ray appliance to another.
