  38 +         This is the highest numbered device created in /dev. You will actually have
  39 +         NR_TTY_DEVICES+1 devices in /dev. The default is 63, which will result in
  40 +         64 /dev entries. The lowest number you can set is 11, anything below that,
  41 +         and it will default to 11. 63 is also the upper limit so we don't overrun
  42 +         the serial consoles.
