The problem is that those bit definitions refer to the HIGH ORDER BYTE
of the io_Status WORD.  This is a bug, and will be fixed.


>#define IOSTB_XOFFREAD 4L
>#define IOSTF_XOFFREAD (1L<<4)

/* change to */
#define IOSTB_XOFFREAD (4+8)L
#define IOSTF_XOFFREAD (1L << IOSTB_XOFFREAD)

That will work.
