Apple probably hasn't documented because they want you to use the firmware. The only reasons not to are speed and functionality - Apple and hardware developers should be able to provide both. If Apple doesn't provide a needed feature (like sending BREAK, for example) in Firmware, let them know how to do it right. [Apple provides for CONTROL and INTERRUPT entry points in newer firmware, firmware developers should agree on what the byte-size command for 'send BREAK' is. Apple needs to provide some guidance in this area.] -- - Ralph W. Hyre, Jr. Copyright (c) 1987 by Ralph W.
