#3800: termios - Add Capability to Generate SIGINTR and SIGQUIT
  Reporter:  Joel Sherrill  |      Owner:  Joel Sherrill
      Type:  enhancement    |     Status:  assigned
  Priority:  normal         |  Milestone:  5.1
 Component:  posix          |    Version:  5
  Severity:  normal         |   Keywords:  termios, POSIX
Blocked By:                 |   Blocking:
 Currently the RTEMS termios implementation does not examine the ISIG
 setting in the termios attributes and thus does not examine input for the
 INTR (ctl-C) and QUIT (ctl-\) characters.

 The proposed solution implements a point at which a default handler can do
 nothing like currently or the application can use the following new method
 which allows them to register the RTEMS provided method

 int rtems_termios_register_isig_handler(
   rtems_termios_isig_handler handler

 The method rtems_termios_posix_isig_handler() is provided and has the
 POSIX compliant behavior of generating SIGINTR for the VINTR character and
 SIGQUIT for the VQUIT character.

 The user also can register rtems_termios_default_isig_handler() to return
 to the default behavior.

 The test termios10 is added to exercise this behavior.
