0x6001 0x114F	AvanstarXp

if your card isn't listed, don't worry.
uarts are generally quite easy to get going.
the main trick for the oxford semi 954-style
chips is to get the base freq correct.

Thank you very much, erik.

Does Plan9 manage PC104 (ISA) cards ?

 From man plan9.ini

I know they are obsolete but  I'm trying to port an
automation system under Plan9 and must deal with
strict hardware constraints.

i understand that it does, but i have never used
an isa card with plan 9.  there appears to be code
to handle isa stuff.  see plan9.ini(8) for some hooks.

I have used an isa card with the 4th edition, so I know they work,
however I haven't tried for quite a few years - it might have bitrotted.
