The code works well, but I want to know where I can improve it to make it more resilient and less error prone. By reverting the condition of if portList. The naming of the variables could need some imporvements too, e.

Storing the result of matchingEntities["DeviceID"]. ToString into a variable will speed up things. I developed an iteration using LINQ instead of the foreach loop while also implementing the improvements Heslacher suggested, the code now looks like this:. Sign up to join this community.

How do I get device information from specific port names?

Recently I was developing a little application that needed to enumerate existing COM ports on a machine and then display them in a menu. Generally, this task is quite simple to accomplish:. However, the tricky part was that I wanted to display human-friendly names that identify the device similar to they way they are displayed in the Device Manager.

As an embedded developer who writes desktop software mostly for configuration of, and data download from, peripheral devices, I use serial data streams a lot. C and the. NET Framework provide a rapid application development that is ideal for early development that needs to track changing requirements as hardware designs evolve.

A Developer. An Eweek. Does anybody have a code snippet? You should start by doing a bit of general research on WMI, which is implement in.

Categories I also have another microcontroller on this board that is sitting and watching usb traffic and interfacing with the propeller and other components. My chief concern is how to find the ftdi part from a windows C environment. I can open a serial port and start walking thru each com port until something answers on the board, but I would like a real solid way to id the ftdi part, and then know exactly what COM port it is setup on. For example, think about Parallax's IDE for the propeller. How does this tool ID the eval board? Very cool, but there doesnt seem to be an interface to get the COM port out of this.

Serial port programming using Win32 API (Windows)

Posted by dariosantarelli on October 18, When using the SerialPort. GetPortNames method, you are querying the current computer for a list of valid serial port names. The port names are obtained from the system registry if the registry contains stale or otherwise incorrect data then this method will return incorrect data. The limit of this approach is that you get just an array of port names e.

Sometimes we require to communicate with an external device like a printer, microcontroller board or any serial device using the serial port of a windows machine. We can use any one of them for serial communication but sometimes we require to create our own custom serial application for communication. In windows, it is easy to create the custom serial application using the win32 API. In this blog post, we will learn serial port programming using the Win32 API. You can also see the below articles that how to change the properties of com-port like baud rate, parity using the Windows API.

FTDI COM Port ID using C# on windows

The modem creates 2 serial ports. The second port is used to get vital information from the modem, such as signal quality; to send and receive text messages; and a whole host of other functions. I am writing an application that will wrap up some of the features provided by the second port. What I need is a sure fire method of identifying which COM port is the spare one. Iterating the ports and checking a response to "ATE0" is not sufficient. The modem's port is usually the lower numbered one, and when a dial up connection is not active, it will respond to "ATE0" the same as the second port.

the proper way to get the port's name would probably be: However, this might require so much interop in C# it's not even funny, so I don't blame you if you.
