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.
