4 mbps irda on 560

[phr@netcom.com (Paul Rubin)]

It's very unlikely that you can upgrade the built-in irda port
on your 560 to 4 mbps.  115 kbps irda is common because it looks
like a standard async port to the computer.  4 mbps is different.
Generally laptop vendors don't do upgrades like this.  They come
out with new models all the time instead.

It's possible that some 4 mbps irda interfaces in pcmcia cards
will start shipping at some point.
