The API has been totally restructured, and the usage does now almost resemble the other SCSI drivers, with the minor exception that you are required to tell the driver about your intentions with respect to the CD-R you are about to burn. There's a wormcontrol(8) utility (usr.sbin/wormcontrol) as well for this. The driver has by now only been tested on a heavily tweaked 2.0.5R system against a Plasmon RF4100 recorder. However, note that this driver is based on some other recent changes in the SCSI code, so you would have a hard time backporting it to 2.1R. Usage of -current is recommended. Fitting hooks for other burners should not be too difficult, but you would best do this only with a certain understanding of the SCSI command-level protocol, and with a SCSI reference manual for your drive. Chances are good that HP or Philips drives could be easily cloned from the Plasmon part, since they are rather similar. Other drives will certainly require more work. There are still a lot of bugs in it, and i consider the driver still highly experimental. Suggestions and discussion about the archi- tecture are welcome. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
