Some platforms are interfaced via serial-like interface (e.g. msim). But
there are some limitations, like it can be a problem if you have a single
device for input and output (as would be the case for a serial port) and in
some cases it's been worked around. There is some major janitorial work
needed to make this work properly with a single device. Also, there is no
mechanism to configure this, e.g. to say you want to use a particular serial
port on your PC as a console.

You can have the kernel console and the log output of user processes
over serial, but it is currently not possible to have full user serial
console (ie. the bdsh over serial), because there are some missing parts
that would connect the uspace serial driver with the input and output
server.
