serial port:how do u determine whether data is sending in?

Posted 05 January 2010 - 08:32 PM

hi, i am currently writing a visual basic program that gets data from a serial port.
everything is connected up but the data is not received until my device on the other side is turned on on the other side.
which condition can i use in my loop to ensure that i only start comparing when i have started to receive so that my loop will not hang as there is no data input?

thanks

regards,
sky

Hey could you give a bit more details I know that you want to use a VB program to establish the data transfer rate but could you add the code so that we could understand you a bit more?

Is this what you are talking about: link
