I need add 16c554 on 9261 system to expand my uarts.
I found there is 16550 driver in wince 6.0 and I think this driver can be used to drive 16c554, like linux. In internet, i can not find a whole solution for this application, please help to tell me how i can do.

even if no one use 16c554, it will be better if can tell me how to add 16550 driver on 9261 system.
how can i make reg file for it?
I use CS0 of 9261, interrupt pin is PC3, I can calculate the IOBASE, but what the IRQ is here?
and i can find com16550, ser16550, isr16550, which one i should use?

thanks!
