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