All Has anybody written a working interrupt-driven routine in JPI v 2.0? I sure would like to know the answers to the following questions! 1. The manual says that the module [priority] on PC systems is a bit mask and then falls forever silent. I assume this mask refers to the IRQs with bit 0 corresponding to IRQ0, but is this correct and is it bit-on or bit-off to disable a given interrupt? 2. What, exactly, is the "interrupt vector" required by IOTRANSFER? An IRQ number, an index into the jump table (0CH for Com1, etc.) or something entirely different? 3. What do the following link error messages mean? SYSTEM$TRANSFER unresolved... _new_priority unresolved... This looks like an installation error on my part, but I haven't a clue as to where these objects might be. Not in SYSTEM as far as I can tell. Any assistance would really be appreciated!
