How to check and use serial ports under linux – this listed my serial port under ttyS0. Listed a huge list of ports that do not exist on the machine.
After the make install of first bullet point TERMINAL example would run. However when I tried to connect it flagged ERROR: Permission denied. It appears that Linux requires super user access to touch the hardware because after doing sudo ./terminal the program connected with the serial port.
