* Description: Execute commands directly to the SCSI drive
* Author: Carl Edman
* Created: Sat May 8 23:07:42 1993
* Modified: Mon Jan 31 13:33:37 1994 (Carl Edman) cedman@capitalist.princeton.edu
* Modified: Sat Apr 08 1995 (Juergen Sell) js@icem.de
+ added support for scsigetdev to start search for wanted drive
at specified deviceId, since my cd-drive is second logical
removable media
* Language: C
* Package: N/A
* Status: Alpha
*
