If you are referring to the host hardware parallel or serial port,
to some extent this can be accomplished by something like the
sid-io-fileio or sid-io-stdio components.  One would tie the simulated
target UART to an instance of one of these host-side interfaces, and
configure the latter to talk to the host's /dev/ttyS1, or something
like that.  There are a few glitches like the new sid-io-fileio only
being capable of output at the moment (oops), but gazing over
sid/component/consoles, one sees that filling these gaps is not that
big a deal.

You need to open a per-component view.  In that list, you'll see
all the avilable attributes.  The value fields are as editable
as the subject components let them.  Most pins are exposed as
attributes for purposes of just such interaction.

Absolutely.  See the hw-visual-tty for a two-way interactive one;
see hw-visual-clock, hw-visual-probe-pin (aka "fuzzy dice") components.
