Previous versions of this Servo Controller Board suffered from baudrate conflicts. The MIC800 chip requires a communication protocol using RS232 @ 2400bds. But the Main Board may not use this baudrate. ASM code needed to switch between two baudrates, in order to get suitable communication with both the PC and the MIC800. More importantly, every chars sent to the MIC800 was also sent to the PC. Because of baudrates differences, this was not a problem, provided the PC frequently flushed chars, to trash invalid received data
