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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

A display driver provides the Control function to give applications direct
access the display driver. Most display drivers only provide support for the
following escapes:
 
♦  GETCOLORTABLE
 
♦  MOUSETRAILS
 
♦  QUERYESCSUPPORT
 
Applications call the QUERYESCSUPPORT escape to determine whether the
display driver supports a given escape.
