setserial can also be used for this surely ?

That's a hack that is only going to work on specific systems where it is mapped the way you expect and doing stuff behind the back of the serial driver.
I'm not averse to a better solution but it needs to be general and maintainable. Is there a way to identify the presence of the windbond CIR device as opposed to an 8250 ?
