-config UNIX98_PTYS
- bool "Unix98 PTY support"
- help
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
- All modern Linux systems use the Unix98 ptys. Say Y unless
- you're on an embedded system and want to conserve memory.

-config RAW_DRIVER
- tristate "RAW driver (/dev/raw/rawN)"

- help
- The raw driver permits block devices to be bound to /dev/raw/rawN.
- Once bound, I/O against /dev/raw/rawN uses efficient zero-copy I/O.
- See the raw(8) manpage for more details.

- Applications should preferably open the device (eg /dev/hda1)
- with the O_DIRECT flag.

- architectures and 24 bytes on 64-bit architectures.
