    Has anyone got the Serial Port Read Timeouts to function correctly using System.IO.Ports.SerialPort??

    I'm seeing that if I set the ReadTimeout value to Infinite, any calls to read the serial port will hang as expected till a character comes in. But If its set to a value in milliseconds, say 600, the calls will return immediately if no data is available and raise a timeout exception.

    have tried setting it to 10,000 thats 10 seconds to ensure it works as you think it does?

    600 is just over half a second which is fairly fast

    I've been using the system tick count, saving it before I do the Read, then when i return i can work out how long the call lasted.

    Something funny has happened, after setting the ReadTimeOut to infinite, then setting it back to a normal value it appears to work now :eek:
