What would be the proper way to handle this? Is it acceptable to probe at it's address whether we have a valid ns8250/ns16550 device (we can read back the divisor and compare with what we have set) and dropping the serial if none is available? -------------- next part -------------- A non-text attachment was scrubbed...
