Don't forget to add options "COM_MULTIPORT" or it won't work very well! device sio4 at isa? port 0x100 tty flags 0xb05 device sio5 at isa? port 0x108 tty flags 0xb05 device sio6 at isa? port 0x110 tty flags 0xb05 device sio7 at isa? port 0x118 tty flags 0xb05 device sio8 at isa? port 0x120 tty flags 0xb05 device sio9 at isa? port 0x128 tty flags 0xb05 device sio10 at isa? port 0x130 tty flags 0xb05 device sio11 at isa? port 0x138 tty flags 0xb05 irq 9 vector siointr The trick in setting this up is that the MSB of the flags represent the last SIO port, in this case 11 so flags are 0xb05.
