Getting legacy pre internet programs accessing the internet without recompiling or modifying source code, Cobol, Basic, DOS etc.
This is a hack, also known as rerouting legacy file system calls to an internet server. If you don't have the source code available for a program but need it to access the network where it otherwise would access files, this can be done provided you know the file formats of the data your program your interested in and simultaneous access to these files from multiple sources isn't neccessary. A typical DOS program which might make use of this technology would be to let a legacy point of sales till update a webshop stock & maybe even able to handle new products uploaded to the webshop. The till would need to the DOS program restarted at set idle times like teatimes, lunch break & overnight to sync with the web server as regularly as possible. File access is exclusive to one program at the time, no concurrency. In DOS you'd do it this way in DOSBox , Modify the DOS/BIOS/kernel( e.g. Linux) or the emulator code ( e.g. DOSBox ), the emulator code would be easier to ...
