Hello, I have tried to find documentation on how to use the CTS and RTS pins currectly. But there are no examples what-so-ever about it. I am interested in using this module in just setting out HIGH or LOW (via the RX, TX, CTS, or RTS pins). I understand that they are Active Low – but how do I set them to be HIGH or LOW? * Does the voltage level depeds on the input power? *
Thanks
