This is therefore a final proof that it is not caused by sending breaks. Dongle that is not present can't send breaks anymore ;-) Cl< On Sun, Dec 26, 2004 at 04:24:26PM +0000, Karel Kulhavy wrote: > On Sun, Dec 26, 2004 at 02:53:35PM +0000, Dr. David Alan Gilbert wrote: > > Hi Karel, > > I wonder - is the board sending a 'break' signal to the PC?
