[Klone-users] klone hangs up

[diakat 2000]

Hi Stefano,

I think that there are mixed different problems.
Yes, in one case we had some empty C strings. This is resolved now.

The other problem is the TCP/IP connection. After some testing and
error handling now klone does not crash anymore.
But I get EINTR (The receive was interrupted by delivery of a signal
before any data were available.) sometimes I request data from the
other program.
Does klone send such signals?

Many thanks!
