Eh. The vector gives an address where the pointer to the interrupt service
routine is located. (Along with the PSW to set).
Interupt priority also exists. The pdp-11 have eight levels, IPL0-IPL7,
the VAX have more, sixteen software and sixteen hardware levels, I think
it was (don't care to look it up right now).

Nope. Wverything works fine, you just get ttyS0 at the other end of the
distribution panel.
