tcload(1M)                   DG/UX 5.4 Rel. 2.01                  tcload(1M)


NAME
       tcload - load terminal controller devices

SYNOPSIS
       /usr/sbin/tcload [-v] controller_node [...] or
       /usr/sbin/tcload [-v] -a

DESCRIPTION
       The tcload command makes asynchronous terminals (/dev/tty* nodes)
       available for use by initializing and enabling the desired terminal
       controller devices in the appropriate way.  For instance, for a SYAC
       device, tcload resets the board, downloads its resident controller
       code, starts it executing, monitors events on the device, and
       responds appropriately to them.  The controllers to be loaded are
       specified by the controller_node arguments.

       If the controller is a SYAC VTC device, the VTC configuration files
       should be set up properly before running this command.  The SYAC VTC
       configuration files are located in the /etc/tcload directory.  At the
       very least, the SYAC VTC should have a device entry in
       /etc/tcload/vtc.addrs.

       Note that the tcload process does not terminate as in pre-5.4
       revisions of DG/UX. It continues to run and react to events on the
       system's controllers.

       The following options are available:

       -v     Print verbose output about the loading process.

       -a     Locate and load all terminal controllers configured into the
              system; this is equivalent to running the command:

                      /usr/sbin/tcload /dev/async/*\)

EXAMPLE
       /usr/sbin/tcload -v /dev/async/0 '/dev/async/syac@61(60020000)'

FILES
       /dev/async/*                   Terminal controller device files

                                      types
       /usr/lib/tcload/models/*/LOAD  Load programs for controller types
       /etc/tcload                    Directory of SYAC VTC configuration
