Ah, the joy of serial communication issues… Been there, done that, got the metaphorical T-shirt. If you’re hunting for a solid COM port tester app, let me spare you some headache with a recommendation: check out Serial Port Monitor. It’s reliable and has saved my bacon more than a few times when things went haywire.
To spice things up with some variety: if you want more than just a single option, try out PuTTY for basic terminal operations or RealTerm if you want some features specifically for debugging and serial data visualization. They’re like the Swiss army knives of serial communication utilities.
On another note, if you want a more comprehensive guide on testing COM ports, worth checking out this Serial Port Testing Guide. Loads of good info there, which could help you get to the root of your issues without random guesswork.
So gear up, fire up those apps, and hope the serial comm gods are in your favor. Cheers!
