                the drive type is insignificant for these devices.

   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, including security. 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.
