Kirk, You are right. I misread the ioscan output. Here are the HW database contents in a more readable form: type driver HWpath Description ------ ------------- ------ -------------------------- ba core_adapter 16 Core I/O Adapter ext_bus CentIf 16/0 Built-in Parallel Interface tty asio0 16/4 Built-in RS-232C ext_bus c720 16/5 Built-in SCSI ... lan lan2 16/6 Built-in LAN ps2 ps2 16/7 Built-in Keyboard/Mouse ba core_adapter 20 Core I/O Adapter tty asio0 20/2 Built-in RS-232C ba eisa_adapter 20/5 EISA Bus Adapter lan btlan0 20/5/8 EISA card INP0500 ... I had assumed "core_adapter" meant LASI. The second "Core I/O Adapter" at "20" must be WAX. > The serial port labeled console is attached to the LASI rs-232 unless an > access port card is plugged into the access port capable slot. ... Ok. We still have an ordering issue then between WAX/LASI and how tty's are numbered/discovered. That's in addition to the problem of interrupts not getting delivered for the serial port on WAX at "20/2". grant Grant Grundler parisc-linux {PCI|IOMMU|SMP} hacker +1.408.447.7253
