I understand that this wouldn't be easy. I don't think I have the
skills to do it myself. I believe that the TCP module in MSKERMIT and
the WATT-32 libraries come from the same origin, but have diverged
substantially over the years, with both originating from work by
Erick Engelke. I doubt that SSH could be added in a 16-bit realmode
program. The memory restrictions shouldn't be a problem if MSKERMIT
were converted to a 32-bit protected mode program. Perhaps someone with
the necessary skills, time, and inclination will tackle the project.
MSKERMIT is still the best available telnet client for DOS.
