The rest of this blog post will simply use ttyUSB0 as the name of the serial port, but you must use the correctly named serial port assigned to your connected device if you are following along. The device name for a serial connection is properly referred to as a serial port. Also, the index number at the end of the name is determined by the devices minor number and may not be 0. There are more serial port names than I mention here. If your system architecture is ARM, you might see a name like this ttyAMA0 and if it is a Samsung, then the device might be named ttySAC0. In my case the TTY device name was ttyUSB0 however, if your cable is not a USB converter, then it might be named ttyS0 instead. usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0 ftdi_sio 1-2:1.0: FTDI USB Serial Device converter detected
