Anthony,

That seems like a reasonable request.

So, a 'info port80' command would be preferable to having i/o port 0x80 be read/write?


Maybe, info debug-port.

I still think the read/write port route would
* better emulate systems,
* be more flexible (allowing software the option to read it),
* and, be easier to implement :)

But, I think the most important part is to make the data accessible somehow. So, the monitor access method would work fine as well.

I don't object to read/write access.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
