Program Menu
When this menu item is selected (or the Program button is clicked) the software will halt the playback of the control box connected to the selected COM port. Once that is done the software then sends header information to the control box. Once that is done then the bulk of the data transfer occurs. When completed the control box should immediately start playback of the new pattern.
The status of the above process is updated in the status bar at the bottom of the software's window.
