Baudrate error?

Hi,

I'm using the serial port on a Pocket PC (Mobile 2003 - CF 2.0) in my
application, but when i try to set the Baud rate like:
MyPort.BaudRate = 115200;

I get this exception:
{System.ArgumentOutOfRangeException: Argument must be between 0 and 65536.
Parameter name: baudRate
at System.IO.Ports.SerialStream.set_BaudRate()
at System.IO.Ports.SerialPort.set_BaudRate()
....}

But I know for sure that my device support a baud rate of 115200 (have used
it several times in other applications)

Any idea what could be wrong??
Your help is highly appreciated!

Thanks,
Ole

Hi,

Did you check the serial port settings in the ctrl panel?

I'm not sure I did understand your question - what do you mean by control
panel (it's a Pocket PC). I did succesfully use a baudrate of 115200 on the
very same Pocket PC by using calls to the API.

Thanks
Ole

Hi,

I do not see this error (though I am using WM5). Can you double-check to
make sure that there isn't a typo?

Hi,

I discovered that the port must be a Bluetooth port to show the error.

Thanks

Hi,

BT speed is not material. I suppose there is some sort of driver error.

Can you trap the error and try another speed? Since BT virtual ports don't
rely on the bitrate, this may work for you.

Hi,

I wrote a message yesterday (called 'Bug report') regarding this issue - the
bug seems to be located in the CF layer as there is no problem when using
the API.

Thanks
Ole

Hi,

I'm surprised that your API call works and the SerialPort call doesn't. The
underlying API should be the same.

Have you tried other classes, such as CFSerial from my homepage, and
OpenNETCF.org?
