Several sub-compact devices do not provide initial output to a video device. A serial console must be used for installation


12 Volts

  • NB many small devices use 3.3 V or 5 V serial interfaces and are likely to be damaged if connected to the conventional COM socket on a PC
    • USB-serial cables are available cheaply and tend to use 3.3 V interface
    • some newer devices require a 1.8 V serial interface
    • Linux generally allocates these as /dev/ttyUSB0


see Terminal_Emulation for suitable apps to use with the serial cable


Banana Pi

  • requires serial console for initial installation
  • default parameters for terminal emulators might not match Banana Pi. The following settings might need to be configured
    • baud rate 115200
    • software flow control Yes
    • LF Yes
    • CR Yes


  • requires serial console for initial installation
  • uses same parameters as BananaPi above

Raspberry Pi

  • most software puts signal to a video port (Composite or HDMI) during initial installation
  • use of a serial console for initial installation is optional
