- Restrict with 31 bytes length for remote and signal name - Don't stuck for 0 PWM cycle timings - Support timings > 65535 PWM cycles - Fix remote file open error - Add IRDA TX debug redirect - Add remote parse error print, improve parsing, support tabs - Fix stucks with uncorrect RAW signal values, long strings in remote file, etc - Fix HAL signals capturing (save previous read value) - Fix leak in case of failed parsing
