标题: FC4下怎样获得串口的地址和IRQ？
google一下，据说/proc/pci下有其信息
但我的FC4下的没有：（

[code]
Serial: 8250/16550 driver $Revision: 1.90 $ 76 ports, IRQ sharing enabled
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered
[/cod]

上面这几句怎么解？是不是驱动有问题？

是串口驱动和I/O调度器的注册
奇怪，怎么没有显示串口信息呢？
