I am looking for a serial port component for .NET that overcomes the issues

  • 0

I am looking for a serial port component for .NET that overcomes the issues with the built-in Serial Port component related to sudden unplugging of USB-to-RS232 adapters, and suspension of the computer while the port is open. (Untrappable errors occurring after the the device is unplugged or the computer comes back after being suspended.)

I have been using Richard Grier’s solution, but I still have problems when resuming from suspend.

Is there a 3rd party component that you would recommend? I have tried several, and each have their shortcomings. Ideally I’d like a drop-in replacement for the standard serial port, but I’ll take whatever I can get.

(Note: I apologize if you find this post a bit vague. This question is targeted to those familiar with my problem… it is a very common issue.)

Thank you for your time.

Edit: It turns out that upgrading to .NET 4 and using the serial class works fine on XP, but does not work on Windows 7.

    While it would be helpful to post which solutions you’ve tried (no sense in someone recommending something that you’ve already ruled out), I can recommend the CommStudio component.

    While it’s a bit pricey, it’s a great component and has done well with a few high-throughput (relatively speaking, of course), highly-bidirectional applications that I’ve worked on, and it’s never had an issue with unexpected device removal.
