Defaut Setting: CONSOLE_BLANK_TIME=''
Typically, the Linux kernel activates the console's screen saver after some time without console input activity. The variable CONSOLE_BLANK_TIME allows you to configure the timeout to be used or to disable the screen saver completely (CONSOLE_BLANK_TIME='0').
Defaut Setting: BEEP='yes'
Causes a beep at the end of the boot or shutdown process.
If you enter `yes' here, there will be a beep at the end of the boot or shutdown process. If you suffer from an extreme shortage of space on your boot media or if you don't like your router to beep, use `no' instead.
Default Setting: SER_CONSOLE='no'
The fli4l router can be used completely without any keyboard or graphics adapter. In order to see all kernel boot messages without Telnet or SS access to the router it is possible to redirect all input and output from/to a serial port by setting SER_CONSOLE, SER_CONSOLE_IF, and SER_CONSOLE_RATE to appropriate values.
The serial console can be set to three modes:
SER_CONSOLE | console input/output |
no | Input and output over tty0 |
yes | Input and output over serial console |
primary | Input and output over serial console, kernel output additionally redirected to tty0 |
secondary | Input and output over tty0, kernel output additionally redirected to serial console |
Changing the value of SER_CONSOLE affects the router only if you also update your boot media or if you perform a remote update of the syslinux.cfg file.
If you disable the serial console, please pay attention to enable an alternative access to the router (ssh or physical console).
You will find further information in the appendix under Serial console.
Default Setting: SER_CONSOLE_IF='0'
Number of the serial port to use for console output.
This variable controls the number of the serial port to use. Zero corresponds to ttyS0 or COM1 in the DOS world, respectively.
Default Setting: SER_CONSOLE_RATE='9600'
Transmission rate of the serial port for console output.
This variable contains the Baud rate to use for transmitting data over the serial port. Reasonable values are: 4800, 9600, 19200, 38400, 57600, 115200
