Depending on your serial device and its software, you may have to configure: a System Preference item (ie modems accessing ISPs), an application (ie UPSes), or some combination of these (ie modems accessing terminals using Zterm).
Please refer to your serial device's documentation on which method your serial device uses and how to access that software's serial port "configuration" screen.
Once you've determined where to select or configure your serial device's software's serial port settings, please proceed to Step 4.
