Hello
I have started to make some tests with the CVS-Version from 07.january 2005.
A bad surprise was: the serial communication from the chess programs with my
chessboard is in the CVS-Version from 07.01.2005 not working. The 1.3.1
version works fine. I have made a debug file and there is a error message
(last line)which probably explains the problem.
Should I open a bug report?
Best regards
Bernhard
