The following setup is along the lines of what you might do for a shared interrupt solution (i.e. to keep your interrupts free for other COM ports or peripherals): device sio4 at isa? port 0x220 tty flags 0x0905 device sio5 at isa? port 0x228 tty flags 0x0905 device sio6 at isa? port 0x240 tty flags 0x0905 device sio7 at isa? port 0x248 tty flags 0x0905 device sio8 at isa? port 0x260 tty flags 0x0905 device sio9 at isa? port 0x268 tty flags 0x0905 irq 5 vector siointr Obviously you would need to set all your addresses to the alternate locations, and set the board to share IRQ's on IRQ 5. I am not sure about the "flags 0x0905" - the 05 may or may not be appropriate (the 09 tells it that the shared IRQ master device is sio9). This is totally untested - I am just trying to get you shoved in the right direction with something I *think* will work. I do not have one of these cards to play with, but multiport cards I have configured in the past all pretty much fell in line this same way. Remember to do options "COM_MULTIPORT" in your config file. Good luck, ...
