Hi Joerg,

The USB to RS232 or Parallel port converters don't retain any timing data.

The Phillips flash utility uses a standard serial RS232 interface so it 
will work.

The MSP is using the serial interface but is probably using the control 
signals for non serial control. If there is any timing required, it may 
be lost by the USB to serial converter.

This is similar for programs that use the parallel port to control 
stepper motor drivers. The generated pulse streams are time critical. 
The USB-parallel converters don't give a stuff about the timing issue, 
and so the timing data is lost.

Cheers,

Peter.

Cheers,
