- INTMon - Interrupt Monitor

- ------------------------------------------------------------
-
- INTMon (INTMON.EXE) was designed primarily to serve as a
- educational tool, and offers brief descriptions for each DOS
- function called via interrupt 21H. Functions are supported
- through DOS version 4.0. Several "undocumented" functions
- are also supported. INTMon actually reports the function
- number just prior to the interrupt request, and returns the
- contents of DS:DX and BX for most file related functions.
-
- INTMon is a memory resident utility requiring approx 16K of
- DOS memory. The program offers the following option switches
- which are to be used on the command line.
-
-
- /U = Unload the current copy of INTMon.
- /H = Help.
- /I## = Interrupt number entered as two (2) hexadecimal
- digits. The default interrupt is 21H.
- /V = Verbose mode. Describes common DOS service
- calls. Only valid when monitoring interrupt 21H.
- /C = Color in which to display the interrupt
- information (1 to 255).
- /P = Pause factor in clock ticks (1 to 18). One clock
- tick equals approximately 1/18th of a second.
- /S = Sound only mode. Sounds a beep on the system
- speaker whenever the specified interrupt occurs.
- /L## = Line on which the interrupt information will
- appear.
-
-
- In order to /Unload the INTMon utility, it must have been
- the LAST TSR loaded.
-
- Exercise *CAUTION* when specifying the PAUSE value as this
- will slow the system considerably, and may upset critical
- system timing mechanisms.

- ***** I M P O R T A N T *****
-
- This program was originally designed for a very specific
- situation which required INT 21H observation. Use this
- program with EXTREME CAUTION when monitoring any other
- system interrupt, and/or when disk caching software or any
- other type of volatile storage facility is active on your
- system. This TSR should not be loaded in HIGH DOS memory.
