Hi Kirk,

This may turn out to be a complicated question, so I am copying the
squeak-dev list also.

Since you are starting with a Cuis image, you will want to add the
class SerialPort from a Squeak image (probably you can just file it
out from Squeak, and file it in to Cuis). This will give you the basic
access to COM ports from your image. I think (but I'm not certain) that
any of the usual VMs (standard VM or Cog) will have the necessary
support for using SerialPort on Windows.

I think that on Windows using USB serial ports is a matter of mapping
the serial ports to something that looks like e.g. COM3:, but I am
not a windows user so I don't know the specifics. Probably someone
on the squeak-dev list will be able to give some advice.
