Important Notice
The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

▀ Bits 8-15 of DX correspond to the upper 8 bits of the device driver
  attribute word.
 
▀ Bit 5 of the device information word for a handle associated with a char-
  acter device signifies whether MS-DOS considers that handle to be in
  binary (raw) mode or ASCII (cooked) mode. In cooked mode, MS-DOS filters
  the character stream and may take special action when the characters
  CTRL+C, CTRL+S, CTRL+P, CTRL+Z, and carriage return are detected. In raw
  mode, all characters are treated as data, and the exact number of char-
  acters requested is always read or written.
