Hi,

this is the first Version of J.Schilling's cdrecord-program for OpenVMS.

I'm using a HP6020-CD-recorder to test the program. Please send comments
to Eberhard.Heuser-Hofmann@uni-konstanz.de.

There is a command-procedure called build_all.com in the [.cdrecord] subdir,
that compiles and links the code. The cdrecord-program is been produced in
[.cdrecord.vms] subdirectory.

Define this program as a symbol via

$ cdrecord:==$disk:[dir]cdrecord.exe

$ cdrecord -help gives an idea about the options, that are possible:

$ cdrecord -help
$41$dkb100:[nb.cdrecord_1_8a9.cdrecord.vms]cdrecord.exe;1: Usage: $41$dkb100:[nb
.cdrecord_1_8a9.cdrecord.vms]cdrecord.exe;1 [options] track1...trackn
Options:
        -version        print version information and exit
        -v              increment general verbose level by one
        -V              increment SCSI command transport verbose level by one
        -debug          print additional debug messages
        dev=target      SCSI target to use as CD/DVD-Recorder
        timeout=#       set the default SCSI command timeout to #.
        driver=name     user supplied driver name, use with extreme care
        -checkdrive     check if a driver for the drive is present
        -prcap          print drive capabilities for MMC compliant drives
        -inq            do an inquiry for the drive end exit
        -scanbus        scan the SCSI bus end exit
        -reset          reset the SCSI bus with the cdrecorder (if possible)
        -ignsize        ignore the known size of a medium (may cause problems)
        speed=#         set speed of drive
        blank=type      blank a CD-RW disc (see blank=help)
        -load           load the disk and exit (works only with tray loader)
        -eject          eject the disk after doing the work
        -dummy          do everything with laser turned off
        -msinfo         retrieve multi-session info for mkisofs >= 1.10
        -toc            retrieve and print TOC/PMA data
        -multi          generate a TOC that allows multi session
                        In this case default track type is CD-ROM XA2
        -fix            fixate a corrupt or unfixated disk (generate a TOC)
        -nofix          do not fixate disk after writing tracks
        tsize=#         Length of valid data in next track
        padsize=#       Amount of padding for next track
        pregap=#        Amount of pre-gap sectors before next track
        defpregap=#     Amount of pre-gap sectors for all but track #1
        -audio          Subsequent tracks are CD-DA audio tracks
        -data           Subsequent tracks are CD-ROM data mode 1 (default)
        -mode2          Subsequent tracks are CD-ROM data mode 2
        -xa1            Subsequent tracks are CD-ROM XA mode 1
        -xa2            Subsequent tracks are CD-ROM XA mode 2
        -cdi            Subsequent tracks are CDI tracks
        -isosize        Use iso9660 file system size for next data track
        -preemp         Audio tracks are mastered with 50/15 µs preemphasis
        -nopreemp       Audio tracks are mastered with no preemphasis (default)
        -pad            Pad data tracks with 15 zeroed sectors
                        Pad audio tracks to a multiple of 2352 bytes
        -nopad          Do not pad data tracks (default)
        -swab           Audio data source is byte-swapped (little-endian/Intel)
The type of the first track is used for the toc type.
Currently only form 1 tracks are supported.

One important point is how the CDR-device is being selected:

dev=i,j,k

where:
i: 0   1   2   3   4   5   6   7 
   dka dkb dkc dkd gka gkb gkc gkd

j: scsi-id
k: sub-lun (usually 0)

As an example:

dev=1,5,2 selects dkb502:

An typical example how to put virtual disk data onto a cd-rom is given here:

$ cdrecord -speed 2 dev=0,4,0 dka200:[000000]vda0.dsk

Be aware that cdrecord has copyright on it.
