Updated version of mTCP

mTCP is a set of TCP/IP applications for personal computers running DOS, including FreeDOS. The latest update is version 2023-01-02: A test version of mTCP that has a fix for bad TCP Explicit Congestion Notification. There is a bug in the TCP library that affects newer machines using TCP ECN (Explicit Congestion Notification). If you try to connect to a machine running mTCP and you immediately get a TCP RESET you might be impacted by this bug. Find it at the mTCP home page. We've also mirrored a copy of the update on the FreeDOS Files Archive at Ibiblio, at /files/net/mtcp Edited to add: The mTCP update does not include source code.
