uart device numbering

[Norbert Koch]

Hello,

I have an embedded system
which is equipped with uart
hardware controlled by the puc
driver. There are no standard
uarts at 0x3f8/0x2f8.

When I boot FreeBSD 8.2
I see my uarts as devices 0..3.
FreeBSD 9 shows them as 2..5.

The kernel configurations are
more or less identical and disabling
uarts 0 & 1 through /boot/device.hints
seems not to change anything.

Is this behaviour expected/wanted?

Thank you,
Norbert Koch

I've been using this patch in both debug and non-debug environments and I have 
not
run into any issues.  Please commit when you get a chance.
Thank you.

Since this is a developers-mostly mailing list, I think you could get a
better response at the freebsd-secur...@freebsd.org list.

Yeah, a bummer for me.

It has to be C because I need to use it from C code in a "C runtime".

Thank you, but all of these appear to be off-mark.
They all are end-user oriented applications for drawing/editing graphs, etc.
While I need a light-weight library for "embedding" graph analysis.

The library sounds interesting, but I need to evaluate the license and
light-weight-ness of it.  EPL is not as long as GPL, but is not as short as BSDL
unfortunately.

Thank you!

What about Prof. Knuth's Stanford GraphBase library? It is in public domain.
And there is a whole book about it!

I'd suggest to do some traffic sniffing when connection is dropped. May be
some other host on network takes your IP address and resets connection?
