mTCP v2023-01-10 by Michael B. Brutman is a set of TCP/IP applications for personal computers running PC-DOS, MS-DOS, FreeDOS, and other flavors of DOS. mTCP needs a 8088 processor (or +), 96 to 256 Kb of system memory depending on the application, ms-dos v2.1 (or +) and a network card (Ethernet adapter, or a device emulating Ethernet) that has a packet driver.

The source code of NetDrive is available on mTCP's web page. It's a Ms-Dos driver to access a disk image (floppy or hard disk) which on another computer on the local network under windows (10 and 11), Linux (x86 or ARM) and MacOS.

If you go on the mTCP web page, you must know that it's a 41 years old PC Jr which is running mTCP own http server.
