Take a look in your kernel config file, e.g. /sys/i386/conf/MYMACHINE: device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr device sio2 at isa? port "IO_COM3" tty irq 5 vector siointr device sio3 at isa? disable port "IO_COM4" tty irq 9 vector siointr You may have to twiddle the IRQ's above and recompile your kernel. Without more information it's hard to say what the problem is. Regards, Brian
