Hi all,

I am need of limiting access to some methods in a class to a single case. I am looking at the use of Mutex but it seems to have some limitations. First if the same thread calls the method twice it would be allowed. This doesn't work for me since all calls to the methods would be coming from the main application thread. Does anybody have any ideas on this?

My class contains several methods that send commands over the serial port. I need to block any additional commands until the serial port responds to the first command. Is there such a thing as a Queue?

Thanks
Tim
