mcd -- Mitsumi CD-ROM driver SYNOPSIS
device mcd In /boot/device.hints:"isa""0x300""10" DESCRIPTION
The mcd driver provides a data and audio interface to the Mitsumi-brand CD-ROM player. The CD-ROM player must be interfaced to the ISA bus through one of the Mitsumi proprietary controller boards. The controller boards supported are the LU002S, LU005S, the FX001 and the quite common FX001D. The mcd driver responds to disk-specific ioctl() commands, namely the DIOCGPART command. Other disk-specific ioctl() commands will return an error. The mcd driver also responds to special CD-ROM ioctl() commands. These commands control the CD-ROM player's audio features. The commands are: CDIOCREADSUBCHANNEL get sub-channel information on current status of disc playing CDIOCREADTOCHEADER get table of contents header CDIOCREADTOCENTRYS gets all of the table of contents CDIOCPLAYTRACKS begins audio playing at location specified CDIOCPLAYBLOCKS fails with error EINVAL CDIOCPLAYMSF begins audio playing at location specified CDIOCRESUME resumes playing a previously paused disc CDIOCPAUSE pauses a playing disc CDIOCSTART begins playing a disc CDIOCSTOP stops a previously playing disc CDIOCEJECT opens the disc tray (there is no support for a corresponding un-eject command). CDIOCRESET stops any play and resets the Mitsumi controller board CDIOCSETDEBUG cause the kernel to print debug messages to the console about the mcd driver CDIOCCLRDEBUG cause the kernel to quit printing debug messages about the mcd driver The ioctl() commands defined above are the only ones that the mcd driver supports. There are other CD-ROM related ioctl() commands (such as CDIOCSETVOL and CDIOCSETSTERIO) which are available and may be supported by future versions of the driver. FILES
/dev/(r)mcd0a accesses BSD partition on the disc. Normally, there is only one file system on a CD-ROM disc. /dev/(r)mcd0c accesses raw device. NOTES
The character-mode devices for the mcd driver should only be used for accessing the audio features of the CD-ROM player as the performance on data is abysmal. The current version of the driver uses neither the DMA or IRQ features of the interface board, although it has an interrupt handler for any IRQ requests that are generated. Until the DMA features are supported, the only interrupts that the board generates are those that are not supported by the driver anyway. SEE ALSO
<sys/cdio.h> HISTORY
An mcd driver appeared in FreeBSD 1.0. AUTHORS
The driver was written by Holger Veit (data part) and Brian Moore (audio part). Changes were provided by Gary Clark II, Andrew A. Chernov, and Jordan K. Hubbard. BSD

cdcd - Command Driven CD player SYNOPSIS
cdcd allows control of a CD player either directly off of the command line or in its own interactive query mode. Invoking cdcd without a command will cause cdcd to enter query mode. Invoking cdcd with a command will cause cdcd to execute that command and then terminate when it is finished. OPTIONS
--device DEVICE -d DEVICE Use DEVICE as the CD device. DEVICE is the device special file name of the CD-ROM device. Do not use a Linux SCSI Generic device. USAGE
The following are the supported commands: play [start track] [end track] [min:sec] If start track is specified, play will play the specified track instead of the first track. If end track is specified, the disc will be played from the start track to the end track. start track and end track may either be part of or an entire track title. If a starting position is specified (in the form min:sec), then the disc will begin playing the specified amount of time into the speci- fied track. One may specify a starting position without specifying a start track or only specify a start track and starting posi- tion while specifying no end track stop This will stop the CD if it is playing. open, eject This will eject the CD-ROM tray close This will close the CD-ROM tray pause This will pause the CD if it is playing resume This will cause a paused CD to resume playing ff [min:sec] This will fast-forward the CD 15 seconds by default, or the specified amount of time rew [min:sec] This will rewind the CD 15 seconds by default, or the specified amount of time next This will advance the CD one track prev This will return the CD to the previous track getvol This will return the current volume settings setvol [left front] [right front] [left rear] [right rear] Sets the CD-ROM volume to the given settings. Most CD players only support the front two channels status Gives only numerical data regarding the CD's status info Gives disc name, artist, current track name, and disc positions tracks Lists all tracks on the CD and their lengths rndplay Plays a random track list Lists all CDs in a CD-ROM changer slot Changes the current CD in the CD-ROM changer edit [name, artist, genre, track no.] [value] Edits information about the disc. You may specify name, artist, genre, or the number of the track you wish to edit ext [track no., disc] This will display extended information about the disc. If no parameter is given it will display information about the current track. Specifying disc will display information for the disc itself refresh This will connect to a server and retrieve information about the CD even if there already exists information about it. Otherwise, this is done automatically by any command that uses disc/track names device [device name] This sets the CD-ROM device cdcd will use in future invocations which don't specify the -d option. cdcd stores this information in your .cdcdrc file. verbose [on, off] This toggles whether cdcd will display everything that is happening (e.g. when accessing a CDDB or CD Index server) quit Exits cdcd sites [refresh, display, add, delete, move] This edits the server list. More specific help on each of the commands is available by typing cdcd help sites submit [e-mail address] This will submit a CDDB entry to a CDDB server access [local, remote, proxy] Specifying local will cause CD information requests to return Unknown for track, artist, and album titles, and will not attempt to connect to any servers. remote will cause cdcd to connect to a server whenever any CD information is required. If you need to use a HTTP proxy, it may be specified in the form proxy url, where url is the URL for your HTTP proxy COMPLETION
cdcd uses traditional readline command and trackname completion. To complete a command, simply hit 'tab' when you have typed a partially completed command. To complete a trackname, first type whatever command you wish to pass a track name to (e.g. play, ext) and then begin with a double quotation mark. Type the beginning of the track name and then hit tab. The track name will be completed for you. cdcd> pl<tab> cdcd> play "See<tab> cdcd> play "See You On The Other Side" REPORTING BUGS
