- art-sy has just sprouted a CD-ROM drive. SCO UNIX (3.2.2, my 3.2.4
- isn't here yet) supports it just fine as a read-only block device,
- but the drive could play music CDs for me too if I could only send it
- the appropriate SCSI commands.
-
- I will shortly have the Toshiba manual detailing those CDBs.
- Once upon a time I found, buried in some DevSys documentation, a
- reference to an ioctl() interface to SCO's SCSI drivers that might
- (it seemed, as I read it) allow an application to send an arbitrary
- SCSI CDB to a supported device. I have not been able to find any
- further documentation to confirm or deny such a feature, though the
- header file /usr/include/sys/scsicmd.h looks sort of promising.
-
- Is anyone out there familiar with this ioctl? How can I get more
- information? Has it changed drastically from 3.2.2 to 3.2.4? If so,
- I'll avoid messing with it until 3.2.4 is running here, which should be RSN.
-
- Thanks!
