I'm reading and writing registers of a I/O board in a loop.
There are 12 read/write operations and then 2 seconds of sleeping.
After a time of half an hour the communication breaks with
errno=110 Connection timed out
The problem seems not be caused by the I/O board, because after
restarting the program, the communiction doesn't work.
The communiction also doesn't work to another identical board.
The communication does not work again before I reboot the
Thanks for your help, Roland
