- | The VModem script has been preconfigured to use **ttyUSB0** as the default serial port name. Usually Raspbian will call its first serial port adapter **ttyUSB0** when using USB to Serial converters, and you will not need to modify this script. However, if the name is something **different**, such as **ttyAMA0**, you may need to update the script to point to the correct serial port name.
