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.
