Following is the stack trace which i got:

at Microsoft.Win32.Win32Native.SetEvent(SafeWaitHandle handle) at System.Threading.EventWaitHandle.Set() at System.IO.Ports.SerialStream.AsyncFSCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOverlapped) at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)

Also i tried to abort the application using Ctrl + C while it was waiting for some data to be read and timeout had not occured.

The application exits and I get the exception after it exits.

Please let me know if its possible to catch this exception in the current scenario.

Hi,

I am writing a serial port communication application using Iron Python. Following is my code:

class serial:

def sendMessage( self, entity, command, endstring ):

        try:
            BaudRate = 9600
            DataBits = 8
            comPort = "COM1"


#create a serial port instance for the desired port as specified
            serialPort = System.IO.Ports.SerialPort( comPort )

            serialPort.BaudRate = BaudRate

            serialPort.DataBits = DataBits

#open the port
serialPort.Close()
serialPort.Open()

serialPort.ReadTimeout = 30000

serialPort.Write( command )

          returnValue = serialPort.ReadTo( endstring )
        except:
            print "error"
            returnValue = ""

serialPort.Close()
serialPort.Dispose()

return returnValue

com1 = serial()
a = com1.sendMessage( "ABC", "2", "B" )

Here if i abort my application using Cntrl + C then i get ObjectDisposedException unhandled though i have provided an exception handler.

Can you please help me with the same.................
