Hi,

I wanted to use UART (RS232) over Ethernet on Windows CE 6.0 R2 device.

Our device has Ethernet connectivity (ethernet port)and no COM port support (no hardware COM port).
Is there any mechanism through which i can expose ethernet as COM to my device (RS232 over ethernet).

On my PC side, we have virtual COM port which expose the ethernet interface as COM to my application.

Thank You

And what would it connect to on the other end?

You might be better to get a USB to Serial device, like FTDI

Thank you for the reply.

Ethernet is the physical interface between my device (with WinCE 6.0) and PC.
Since UART can only be used as point to point interface and would connect only once device to server (PC), we are using Ethernet as the physical interface between our server (which contains virtual COM ports over Ethernet) and multiple devices (which should expose Ethernet physical layer as COM to the application running on it).

On the server, we already have virtual COM drivers (UART over Ethernet implementation) and for the implementation on the device side, are there any already existing things (like virtual COM drivers) in Windows CE 6.0 using which we can proceed further.

Thank you

you can see some sample virtual com ports implementation on various devices
in windows CE 6.0.
\WINCE600\PRIVATE\WINCEOS\COMM\BLUETOOTH\RFCOMM - This is serial port
emulator on Bluetooth device.
\WINCE600\PUBLIC\CELLCORE\710MUX - This is GSM MUX driver produces virtual
com port.

All the drivers are tightly coupled with the corresponding devices. you can
get some idea about the implementation of the virtual com ports drivers. you
have to start your own driver from the begining.
