I know of at least two native DOS TCP/IP stacks:
- The Microsoft TCP/IP stack, as delivered with MS LAN Manager
- THe IBM TCP/IP stack, as delivered with OS/2 LAN Server
I believe both stacks are almost the same.
Furthermore, using Windows for Workgroups, you have a "virtual" stack
for DOS (which uses the Windows part as "back-end"). All three are
compatible with one another.
Furthermore, I believe that the DOS box of OS/2 or Windows has a virtual
TCP/IP stack, too.

I will have a look.

Yes, I know. That's the reason I mentioned ssh in the original post.

Well, I know, as I have used it that way before.
In fact, the DOS project started using a RCS implementation for DOS. As
the project has all files in one directory, this is not that bad.
As I wanted to have all sources on a central server, which is backed up
regularly, I moved all RCS files into a central CVS repository. Although
I can share the sandbox between Windows and DOS, there are many "manual"
steps involved, which are error prone:
1. Check out a sandbox on Windows, put it into a Windows share
2. Copy the files from the Windows share to DOS (via network)
3. Work on the files
If I want to check in, I have to do:
4. Copy the files back to the Windows share
6. perform steps 2 und 3 from above
Although it might be possible to checkout directly into a share from
DOS, I do not like that idea. I do not trust the Windows TCP/IP stack
that much, as it is rather old.

Well, as this project started on plain DOS, it only uses features
available on it.
