DIO-17:UART.generateBreak() is not implemented correctly
Summary: This change resolves an issue with invalid DIO implementation of UART.generateBreak(...) method. The result of the call to ioctl(..., TCSBRKP, positive) is undefined. Instead, an approach with the sequency is taken: ioctl(..., TIOCSBRK, 0); followed by usleep() followed by ioctl(..., TIOCCBRK, 0);
