How to do heatsink calculation and determine whether a heatsink is required or not? I know I can cat the output from /dev/ttyS0 but only one way communication is possible that way, from the port to the console. UART data transmission speed is referred to as BAUD Rate and is set to 115,200 by default (BAUD rate is based on symbol transmission rate, but is similar to bit rate). Like all devices, UNIX provides access to serial ports via device files. Why is a 21.10 built binary not compatible with 21.04 install? Once any necessary serial port drivers are installed, you're ready to use the FT232H as a USB to serial UART. It's usually just screen /dev/ttyS0
