Direct serial IRQ broken?

Direct serial IRQ broken?

[Joe Krahn]

A while ago, I was unable to get emulated serial port access
working, but direct port/IRQ access was OK. I downloaded the
lastest testing version, which works under RedHat 9, but
DOS isn't getting any serial port IRQs. I switched to the
emulated mode, and that works now.

I think a recent chage to fix the emulated serial port
broke the raw IRQ access.

Other than that, I've had no problems under RH9.

I suspect those were the different
ones. The patch that fixed an
emulated access for you was probably
this one:
http://sourceforge.net/tracker/download.php?group_id=49784&atid=457449&file_id=43528&aid=693722
and the one that can potentially
break the direct IRQ is probably
this:
http://sourceforge.net/tracker/download.php?group_id=49784&atid=457449&file_id=42853&aid=689297
but I don't see anything obviously
wrong with it.
Could you please play with that two
patches to see how they affect the
problem and verify if the direct
IRQ access was OK in 1.1.4.14 and if
it wasn't, then in what version it got
broken exactly?
