Larry, If what you are talking about is the Kronos board's dropping of serial data, then I ran into it at first with my new Kronos board. But the REASON and SOLUTION for this "problem" *IS* documented in the manual. In the file "DevSetup" (where the device setup info is stored) there are two basic areas – the "Initialize Handler" and "Initialize Unit" (there can be more than one of each of these, depending on the connected hardware). In *both* there is something called "Flags NoDisable_IRQ" , (or "Flags Disable_IRQ"). Both sections say the same thing – "Hold Of (should be off) Interrupts. This attribute allows the user to select between 'Disable' and 'NoDisable'. When Disable is selected, all system interrupts will be held off during SCSI bus data transfer and processed when SCSI transfer is complete. This provides Maximum SPEED at the cost of jerky mouse movements during hard disk activity and the inability to reliably operate most telecommunications programs while hard disk activity is in progress. When 'NoDisable' is selected, all operations will act normally, but some minor speed degradation (single digit percentage – depends totally on applications in progress at the time) will may (their wording) occur with some hard drives. Selecting the 'Disable' here will over-ride the GLOBAL selection of 'NoDisable' made in the 'HANDLER' Initialization. If the GLOBAL selection is set to 'Disable' it can't be overridden by any setting here." <continued>
