Get the name of the com port and the devices connected to it
Pages: . Getting SerialPort name of Arduino device in C. I tried using this link method, but it returned null. I posted the same question on stackoverflow and received this answer: Quote. Hi If your port is not named it will be Null. Code: [Select]. There is also a Button that closes previous selected and opens selected port. The example is spiked with comments so beginners can understand what is going on. Greets, Groover. I've never seen SerialPort. GetPortNames return an empty list when an Arduino is plugged into my or any other computer.
That reeks of a driver issue, a bad cable, or some other un-good thing. I'll take this opportunity to mention that the. No legacy serial headaches! But if you're determined to go the legacy serial route, I'd vote for one of the following options: 1 Do SerialPort. GetPortNames which should work fine unless something's messed up and just use the result to populate a drop-down menu.
Then allow the user to pick the COM port. Any mistakes are on them at that point. Devise a data stream format that includes an identifier for your device. Optionally have a brief conversation with your device to prove you've found it. SerialPort is a major reliability headache, though. Things like surprise-removing your device while SerialPort is reading it will damage the internal state of the object in ways that you, the consumer, can't detect the non-managed stream object gets freed , and afterwards you're holding a ticking time bomb.
The most common symptom is that your app crashes on close because the garbage collector tries to re-free the stream this issue has been know for years and not fixed by Microsoft. There are all kinds of embarrassing workarounds, like calling GC. SuppressFinalize on the stream members, which seems to work But again, I find that the reliable thing is just to avoid legacy COM altogether. The art of getting good answers lies in asking good questions. Quote from: PaulS on Feb 19, , am.
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.
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.

FTDI COM Port ID using C# on 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.
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.

How to get friendly names for COM ports in C#
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. Well, this turned out to be a little more complicated than I thought.
