xcd - Motif based CD player control panel
xcd [-options]
Specifies the raw device name of the CD hardware. If this
option is not specified xcd uses the device name specified
by your CDROM environment variable. Print the current xcd
version number Specifies the color of the window's border
(color displays only). The default is specified by means
of the Session Manager's Customize Window dialog box.
Specifies the color of the window's background (color displays
only). The default is specified by means of the Session
Manager's Customize Window dialog box. Specifies the
display screen on which xcd displays its window. If the
display option is not specified, xcd uses the display
screen specified by your DISPLAY environment variable.
The display option has the format hostname:number. Using
two colons (::) instead of one (:) indicates that DECnet
is to be used for transport. The default is :0. For more
information, see X(1X). This option is the same as the -d
option. Specifies the color of the text (color displays
only). The default is specified by means of the Session
Manager's Customize Window dialog box. Specifies the font
for all of the xcd menus. This option is overridden by the
file.
The xcd command displays a graphical representation of a
compact disk player's control panel using X-based Motif
windows. The display includes a main key pad with keys
for PLAY, STOP, PAUSE, EJECT, NEXT TRACK, PREVIOUS TRACK,
DISK ACCESS LOCK, REPEAT MODES, SHUFFLE MODE, and QUIT. A
status window displays track and time information. A set
of selection buttons, one for each track of an inserted
CD, allow you to directly select a track to be played.
The selection buttons double as a display of the play
sequence with track now playing highlighted. A volume
slider adjusts output volume across a scale of 0-100. The
volume control on the CD drive itself should be set to
full.
To use this program you need a workstation with a Compact
Disk drive. The xcd program is not supported.
Most of the buttons on the control panel are self-explanatory.
One, however, may not be obvious. The padlock button
may be used to disable the eject button on the front
of the CD drive. This can be used to discourage someone
from ripping off your CD.
You can customize some aspects of xcd's appearance by
specifying xcd resources in your ~/.Xdefaults file. Use
the Xcd file as a template. This file is found in the
/usr/lib/X11/app-defaults/ directory.
xcd will attempt to find the cd player on your machine.
If you have multiple CD-ROM players on your machine, it
will use the first one found. The method it uses is to
start scanning the bus using CAM from low to high, so the
lowest numbered CD-ROM on the lowest numbered bus will be
the selected device. To override this selection, set the
environment variable CDROM or the -cd option which will
override this mechanism. For the automatic location of
the CD device to work you must have read permission on the
/dev/cam device. As superuser you should: # chmod 644
/dev/cam
You will need to have the permissions of your CD-ROM
device changed to allow proper operation. In our example
we will use /dev/rrz4c. As superuser you should: # chmod
666 /dev/rdisk/dsk4c
You can tell xcd where the CD-ROM drive is. You can do
this by either setting the environment variable CDROM to
the device, or by starting xcd with the -cd option. For
example:
# using the environment variable (csh) % setenv
CDROM /dev/rdisk/dsk4c % xcd
# using the '-cd' option % xcd -cd
/dev/rdisk/dsk4c
Or you can let xcd figure out where the CD-ROM is.
