module to supply termios methods to IO::Handle objects

 The IO::Termios class extends the generic IO::Handle object class by
 providing methods which access the system's terminal control termios(3)
 operations. These methods are primarily of interest when dealing with TTY
 devices, including serial ports.
 .
 Linux supports a non-POSIX extension to the usual termios interface which
 allows arbitrary baud rates to be set. IO::Termios can automatically make use
 of this ability through the Linux::Termios2 module which is already in Debian
 as package liblinux-termios2-perl. This module will be used automatically and
 transparently to allow set*baud methods to set any rate allowed by the
 kernel/driver.
