Spy-MSDOS
A TSR for snooping MSDOS I/O operations. Written in 1996-1997, still useful today with DOS emulators :-)
Assemble and link with Turbo Assembler (TASM).
tasm spy.asm
tlink /Tdc spy.obj
/Tdc is for generating a COM file
Spy will generate I/O operations dump file in C:\SPY.LST
Run it once for installing. Run again for removing (if possible)
Output example: capture of TASM/TLINK generating spy.com
