>"Many DOS applications that use TCP/IP use a TCP library rather than a system driver, and FreeDOS has two that are compatible with the Crynwr packet driver:

mTCP, still supported and accompanied by a handful of utilities (including an IRC client), and the venerable

Waterloo TCP (WATTCP) developed in the early 1990s."

mTCP is small enough to be used easily on DOS systems all the way back to the original PC. I have several XT class systems which I have restored. I have a few 8-bit ISA NICs which I use along with the FTP server provided with mTCP to transfer files to them.
