This command re-programs the MCU with a firmware image that is already stored in Flash memory. While programming a bunch of dots is printed to the current I/O interface.
If the single argument "RUN" is given, the module restarts after programming completes. Without RUN, the module must be restarted manually.
There's no return value because the old firmware is overwritten.
PROGFW RUN
Re-programs the MCU and reboot
Never invoke PROGFW if you are not sure that a valid firmware image is loaded. See LOADFW also.
