COMports are the "usual" serial ports that one finds on the motherboard these days and on a "multi-io" card in the old days. > device sio2 at isa? port "IO_COM3" tty flags 0x585 vector siointr > device sio3 at isa? port "IO_COM4" tty flags 0x585 vector siointr > device sio4 at isa? port 0x1f8 tty flags 0x585 vector siointr > device sio5 at isa? port 0x1e8 tty flags 0x585 irq 9 vector siointr These are mutiport cards, and they can share interrupts _only_ because they have the hardware to do it. This hardware is NOT usual on a "normal" COMport.
