First, i've made a project which is working everyday since few months ,
and my customers seem to enjoy it. This project is based on a strong
socket commnication between a Rev specific IDE and a PerlScript application.
The comm is bi-directional and is heavily used in both side.
It works on PCs, and : So far, so good.
I could suggest humbly to check all the possible errors from every commands
and functions related to sockets. And probably, avoiding to close the socket
just after having send some datas, or could the client, after
receiving his datas send a message asking the server side to close ?
This reminds me an old story : like you put "[EOT]" as a marker, i did the
same but put a Return char ( cr ) at the end of my marker, and this resolved
one problem i had, but i don't remember exactly which one :-( IT could be
that it was a specific Perl problem, but i would not bet on this one...
Hope this help
Best regards, thierry
