* by Vassilis Serasidis <avrsite@yahoo.gr>
* This HID bootloader work with bluepill + STM32duino + Arduino IDE <http://www.stm32duino.com/>
*
+* Modified 4/24/2020
+* by Eric Callahan <arksine.code@gmail.com>
+* This version of hid-flash has been modified to work with Klipper.
+* The serial port argument is now optional. If entered and found this program
+* will attempt to force Klipper jump to the bootloader by connecting at
+* 1200 baud and enabling DTR.
