done -- but ISR still doesn't run. my test device is preety chatty on
TxD line, so I see both 0x08 (change of serial line status signals) and
0x06 code in Interrupt Identification Register -- exactly as I expected.

but 'voilatile unsigned int c' variable is still 0 -- so isn't
incremented in ISR as it should be.

I was trying both with and without serial driver, both -2.0 and
-current.

As it was written -- I have ISR working on another PC machine, but only
on that one (unfortunately I don't own it any more...) Now I try to get
it work on three other machines and nothing happens.

Hardware is 100% OK -- it works great under Linux and FreeBSD.
