5.4 Command Line Terminal Programs (Including TeraTerm)

should typically be recognised as a ‘USB Serial Port’.
It is necessary to modify several settings to view the data and simplify the end-of-line character requirements of
software commands (i.e. remove the requirement to type <cr><lf> at the end of all commands).
