RE: IO Exception upon opening COM port on Ebox2300

HI toast,
I dont have a ebox and have never used one but I did look around a bit and find that
the ebox-2300 may have 2 com ports. Com-1 is defaulted to the console and will have
to be finagled to be usable. Here is a link here on the forum that is related.

I hope you get yours working. There is a lot of related info out there.

I have the same exact problem. I double checked all my code for parameter errors when declaring the serial port, and they're all correct. I even compiled the program on my desktop and it worked!

For some reason when I try to run the program on the Ebox2300, i get an IOException at serialPort.Open()...

Does anyone know why this is?

IO Exception upon opening COM port on Ebox2300

[font=""]Hello,

I am trying to access either of the serial port of Ebox2300 but IO Exception is raised at sp.Open(); line of the following program:

[code]
SerialPort sp = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One);
//SerialPort sp = new SerialPort("COM2", 19200, Parity.None, 8, StopBits.One);
//The error is raised even if I change COM1 to COM2
if (sp.IsOpen)
{
sp.Close();
}
sp.Open(); // Here exception is raised.
sp.Close(); [/code]
---------------------------------------
I have downloaded ICOP_Vortex86_60CS_BSP.msi and built my image as per eBox-2300 Jump Start Guide.
I have added Serial Port Support, Com_Card, Com16550 and Com16550 (Second Instance) in addition to the items mentioned in Jump start guide.
To test that cable is properly working, I created a Direct connection for COM1/2 on WinCE running on Ebox2300. And then connected the other end of serial port to my PC. On hypertrm, it shows CLIENT CLIENT... which indicates that serial cable is working correctly.
I have also checked that whether COM1 is mapped to COM2 for output by connecting cable to COM2 but writing COM1 in the code, but here also it raises the IO exception at sp.Open(); line.
Your help will be greatly appreciated.
Thanks!
