help with port sensing program

[rppprez]

thats one of my problems i'm not exactly sure how to catch the data coming in I know it connects to the usb port via the development board. then it uses a program called xctu. But i'm not sure how the data is then distributed by that program.

So what does this thing do, anyway?

This is how you know what device to write to....

Every NIC card on your system has a unique identifier in the registry.

Go to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards.

Then there will be subkeys for each card. For instance if there is subkey 2, go to it and you will find a description and ServiceName.

The ServiceName allows you to access the device.

according to digi the manufacturers they said i can treat the data coming in like it coming in from a com port so as long as the baud rate is correct i can retrieve the data. no my question is how do i get that data using the baud rate and the com port any help would be greatly appreciated

thanks in advanced

Yech...I have no idea, to be honest. I've never dealt with port I/O and stuff, mainly because I have nothing that does that sort of thing, except maybe the Internet and a few other bland devices. I guess you can try like MeTh0Dz said (i.e. use WinAPI functions CreateFile, ReadFile, etc); if that doesn't work, I don't know what to tell you.

CreateFile()
ReadFile()

Use CloseHandle() to close the handle once you're done. Read the corresponding registry keys (outlined by MeTh0Dz above) to find the device name, then use the device name as the "file name" when calling CreateFile(). Make sure you set read and write privileges.

There is some documentation on doing this.. I think I saved it on my box, I'll look around for it.
