help
FDC channel number to use for KGDB.
config NULL_TTY
tristate "NULL TTY driver"
help
Say Y here if you want a NULL TTY which simply discards messages.
This is useful to allow userspace applications which expect a console
device to work without modifications even when no console is
available or desired.
In order to use this driver, you should redirect the console to this
TTY, or boot the kernel with console=ttynull.
If unsure, say N.
