Reading/Writing data from/To Handheld device which is connected through serial port

Hi All,
I am writing code for handheld device using WinCE.

My problem is, i have to read/write a text file from/to a desktop machine to the handheld device, which is connected through serial port of desktop machine.

please help me anyone to find out the solution of it.

I have tried to connect the device to the desktop machine but how to read a specified file which is on desktop location from here.

Do you want the device to read a file from the PC or the PC to send a file to the device? These two approaches are fundamentally different.

If you want the device to read that file without user interaction, then you have to write a special device driver or a monitor program that would listen for requests from your device and provide the file.

no not like that, my application will be on handheld device when user enter a key, application should read data from the specified location of the machine, which is connected to the device through serial port, and vice versa.

please guide me i stucked here.
