No I don't. Interrupt signals on a peecee are active logic, not wired or. If you try to put multiple peripherals on a single IRQ you create bus contention. You can throw as many dumb COM ports into the system you'd like, as long as you have unique interrupts and i/o addresses for each. SCO configures in only the first two COM ports - the rest you need to add yourself. -- Chip Rosenthal 512-482-8260 | Unicom Systems Development | I saw Elvis in my wtmp file. <chip@chinacat.Unicom.COM> |
