CSTritt 116:8990686eedf5 3 This function uses ANSI/VT100 escapse sequences to change text to blue. Serial
CSTritt 116:8990686eedf5 4 object must be passed by reference (since it is physically unique and can't be
CSTritt 116:8990686eedf5 5 copied). The call will look normal as does the usage of pc here.
