When running a program in the debugger, what would cause it to crash without
any error messages? I get "The program has exited with code 0 (0x0)".
The program is a MDI app with threading for several serial ports. It only
crashes when data is being received on one or more of the serial ports.
Could someone please give me some ideas about what would cause a program to
terminate in this way?
Thanks....

I need help using the serial port under VB.NET. I found a control called
AxMSComm which I assume is the comm control, but there's no
documentation in my MSDN help. Where can I find descriptions of the
methods and properties of this control? And why doesn't MSDN have it?
Thanks

When I try to use a System.IO.Ports.SerialPort object to read from a serial port, half of the time I have no problems. However, after I successfully read from the serial port, then close the connection, either when re-opening it (in the same instance or a new instance of my program) I get either an IOException "The Handle is Invalid" exception or an ArgumentException "The portName is invalid.
Now, I get the port name by doing this:

HELLO ALL
I am new in serial port programming. I am currently doing a program
that communicates to DSP board through COM1 port. But I am using
Microsoft Visual Studio 2005. The language that I am using is C#. I am
using the built in class SerialPort provided by Microsoft. When I send
some bytes to the output buffer they always appear somewhat later at
the input buffer...
This is really frustrating.I know how to turn off the local echo...

Hi,
i'm trying to set the serial port.(XP SP2, Visual Studio 2005). I use
the example code from MSDN "configuring a communications resource".
CreateFile pass through, however GetCommState return 0.With
GetLastError(), i get the error number 87, which means
"ERROR_INVALID_PARAMETER The parameter is incorrect. "
I'm sure the serial port works, because i can use another program to
read/write through it.
