Tx port is constantly high even after enabling serial communication
@clawson   I have actually copied that header file directly from here: https://github.com/vancegroup-mi...   With some modification to include the `0x20` offset yes. It...

How is a binary value of "0" transmitted in serial communication?
@Jim   Thank you so much for the details. This is actually pretty much how I had pictured it in mind. Could I ask which part of my conversation sounded misleading? Oh maybe i...
