Yes, I saw that, but I get "-5" as error code (I forgot to write that in
my last posting) and I don't know what it means. At the dokumentation
there are only 4 possibilities:
-ETIMEDOUT
-EINTR (interrupted explicitly or by signal)
-EAGAIN (no data available in non-blocking mode)
-EBADF (device has been closed while reading)
