INT 2fH aexxH: Command Processor Command-Line Hook

                                                 Compatibility: ◄Undoc► 3.0+ 

 This MUX interrupt is ◄undocumented► through DOS 6.0.  It is intended
 as way to intercept commands submitted to the DOS command processor
 (COMMAND.COM).  A TSR hooked into the chain can examine a command line
 and decide to pass it on (do nothing) or process the command its own way.

 For instance, this provides a way to implement additional "DOS internal"
 commands and/or keep users from executing dangerous command such as DEL
 or FORMAT.
