I didn't look at them very carefully, but yes, they did look kind of
awfully similar in that way.

Hmmm, wouldn't, say ftp and telnet and so on use winsocks?   I basicaly
don't have any 32 bit windows stuff except juno, but I have somewhere on
a tar.gz WFW 3.11 that I think will have all those little apps in 16
bit versions I can mail you if you like.  Maybe even some 32 bit ones
from a freebie AOL CD.  I guess any windose browser would use winsocks,
too, netscrape if you want a big app, but I think to start ftp or telnet
might be easier to test in controlled conditions.  I have 32 bit ftp.exe
and telnet.exe - maybe wfw 3.11 didn't come with those?

Juno is bount to a provider, but the basic mail service is free.

I'll see if I can do some useful tests.

Any time I send something, the app looks for something to receive too.
Anyway, it won't consider a send done unless it receives an
acknowledgement, I think.

Just once, I think.
