Pseudoterminals (PTYs)
Pseudoterminals, or PTYs, are used to create login sessions or provide
-other capabilities requiring a TTY line dicipline (including SLIP or
+other capabilities requiring a TTY line discipline (including SLIP or
PPP capability) to arbitrary data-generation processes. Each PTY has
a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named
/dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by
