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 ?
