Click-click-click-click…

The clicking was the motor moving.  I fixed the serial port reading issues, so now it doesn’t hang after the first command.

Unfortunately, the clicking is the motor turning on and turning off very rapidly.  I can send commands and see the servo turn.  Very very slowly…  I think it’s reading the command in one cycle, so it’s sending the command to the motor, then in the next cycle, there’s no command, so it shuts the motor down.  Gotta take care of that.
