I just learned about these pins. I wasn't making use of CTS in my program up till now, and I found something odd about my LCD. The CTS pin always returns false. I configured and connected my old LCD module to check to see if it was any different. You can see the difference below.
>>> import serial >>> f = serial.Serial("/dev/ttyUSB0", 115200) # Old LCD >>> f.isOpen() True >>> f.getCTS() True >>> f.close() >>> f = serial.Serial("/dev/ttyUSB1", 115200) # New LCD >>> f.isOpen() True >>> f.getCTS() False >>>
