hey i want to fdump the code to p89v51rd2 mc thru flash magic but when i try to do it it says "unable to communicate.(in use).please ensure that com1 port is not used or try lowering or increasing the baud rate." i tries everything but it is not working what to do?
Can Hyperterminal open the serial port?
If it also fails, claiming that the serial port is in use, then you have to exit program after program until you find which program that has taked the port.
take cover, incoming rant :-)

too often I had to reset my PC to get WinXP to understand that NOTHING is using the comm port, actually (at least, as far as I could see!).
It really is stupid that apps like this don't tell you which program (they think) is using the port!
The information must be available, because I have a serial port sniffer that manages to say which application has the port open: www.serial-port-monitor.com/
