I get the same error as yours on the client side. "Broken Pipe" is only
on server side. We get "connection reset by peer" only after the server
crashes.

I'm not so sure, because I have never seen that "Broken Pipe" error
before now on my computer. Furthermore I don't get any crashes while
running similar client/server Ada programs using T'Input/T'Output or
Receive_Socket/Send_Socket on the same computer.

If it can help in investigating this issue I can post these other
programs too.

As a consequence I must think I am missing something in that specific
code. Please help me to spot what I'm doing wrong.
