I have 2 PC's, 1 for DOS and 1 for XP, both are used for bench programming and they are communicated using serial port, now I would like to use single PC, which can handle DOS & XP and there communication
1) How can make internal communication between DOS & XP ?
If the command prompt window does not run the DOS program then you'll probably have to resort to running dosbox https://www.dosbox.com/information.php?page=0, which is used to run old dos games (which almost never run under a command window).
