{These are the constant definitions used with QIO calls.  First is a
 set of common function codes.  They can be ANDed by just adding them. 
 This is not meant to be all inclusive - just the common ones. 
 NOTE that all values are given in octal.  See the IO DRIVERS REFERENCE
 manual for more info - chapter 1 for general info, chapter 2 for
 full duplex terminal driver, and appendix B for all IO and status codes.}

{ Selected I/O status codes - are done as unsigned bytes, thus
  you can directly compare them to IO_STATUS_BLOCK.BYT[1], and also
  use them in a case statement.   Remember, we only try and define
  the most commonly encountered codes.  You are free to define
  additional ones in your own program. }
