- the 1st through 16th series of 16 pseudo-ttys each, and

- Older versions of the Linux kernel used this major
- number for BSD PTY devices. As of Linux 2.1.115, this
- is no longer supported. Use major numbers 2 and 3.

- 6 char Parallel printer devices
- 0 = /dev/lp0 Parallel printer on parport0
- 1 = /dev/lp1 Parallel printer on parport1
