I haven't been able to get the Plus/4 ACIA emulation to work
in VICE. The rom emulation knows about the ACIA, and will
let me open a channel to it, and sets the command and
control registers, but it doesn't actually do anything, such
as generating interrupts.  I tried the +acia command line
switch, but then it doesn't even let me open the channel.
It errors out with Device Not Present.

If you know of a way to get 6551 emulation to function,
please give me the exact sequence of what I need to do.
