       int BRLAPI_STDCALL brlapi__resumeDriver (brlapi_handle_t *handle)

Detailed Description
       If the application wants to directly talk to the braille terminal, it
       should use Raw Mode. In this special mode, the driver gives the whole
       control of the terminal to it: brltty doesn't work any more.

       For this, it simply has to call brlapi_enterRawMode(), then
       brlapi_sendRaw() and brlapi_recvRaw(), and finally give control back
       thanks to brlapi_leaveRawMode().

       Special care of the terminal should be taken, since one might
       completely trash the terminal's data, or even lock it! The application
       should always check for terminal's type thanks to
       brlapi_getDriverName().

       The client can also make brltty close the driver by using
       brlapi_suspendDriver(), and resume it again with brlapi_resumeDriver().
       This should not be used if possible: raw mode should be sufficient for
       any use. If not, please ask for features :)

       Leave Raw mode

       Returns:
	   0 on success, -1 on error

   ssize_t BRLAPI_STDCALL brlapi_recvRaw (void *buffer, size_tsize)
       Get Raw data

       Parameters:
	   buffer points on a buffer where the function will store the
	   received data;
	   size holds the buffer size.

       Returns:
	   its size, -1 on error or signal interruption

   int BRLAPI_STDCALL brlapi_resumeDriver (void)
       Resume braille driver

       Returns:
	   -1 on error

   ssize_t BRLAPI_STDCALL brlapi_sendRaw (const void *buffer, size_tsize)
       Send Raw data

       Parameters:
	   buffer points on the data;
	   size holds the packet size.

       Returns:
	   size on success, -1 on error

   int BRLAPI_STDCALL brlapi_suspendDriver (const char *driver)
       Suspend braille driver

       Parameters:
	   driver Specifies the name of the driver which will be suspended.

       Returns:
	   -1 on error
