 *        Driver information for common and random access devices.
 *
 * Written by Paul Pierce, 11-27-79.
 * Modified 1-21-80 for WORD level.
 * Modified 6-4-80 to reflect buffers/unit in radev.
 * Modified 11-18-80 for release III:
 *        move num$buffs to DUIB
 *        remove common driver literals
 * Modified 20apr86 to include time out for Timed Wait for Interrupt Support
 * Modified 8-1-86 to include additional fields for message-based devices.
 * Modified 24 Jan 89 - Optional 32-bit support.
