SerialConsole
A computer terminal that uses the serial ports as the physical link for input.As old as
Methuselah but still useful for accessing remote computers (and that includes some access points - (minitar).It's used when there is no need for a physical terminal (monitor and keyboard) or it would be impractical to have one and while it's a slow protocol, when compared to Ethernet, it's fast enough for typing and text display.
While Telnet or SSH are well suited to the task they require a working ethernet connection, a serial links offer redundancy as it uses the serial port (ttyS- or Com port) . For a computer/access point located in an inaccessable location (mounted on a mast or in a roof cavity) redundancy becomes especially important
Under Linux, the kernel may be compiled to load a
serial as console on boot up. This allows the bootloader Grub or Lilo to be accessed and the display of all the boot messages via the remote serial terminal.
