The static variable ui_Command is as of right now being cleared to a
value of zero between everytime that it writes to a port and then takes a
new value from a port. Seems like this zeroing is unnecessary, so we can
just remove these lines.

The description is slightly wrong as the variable isn't static storage class.

This sort of thing seems like a copy/paste sort of error to me, but there
could as easily be some reason here that I'm missing that this is needed
here. My first impression, however, was that this extra clearing is
useless.

Yes, the extra clearing was useless. There are also some useless initializers for this variable and others.

Fine, apart from the description.
