Can someone recommend a reliable COM port redirector?

Trying to connect remote serial devices over network and need a good COM port redirector for Windows. I’ve tried a couple free tools but they either didn’t work or had connection issues. Would appreciate suggestions for stable software that’s easy to set up and works well for remote access to serial ports.

Long-Distance Serial Port Access: How I Finally Stopped Pulling My Hair Out

Alright, so, picture this: you’re sitting at your desk, cable mess everywhere, and you need to tinker with a gadget that’s halfway across the lab—of course, it’s got a stubborn serial interface. Been there. Stretched more than a few USB-to-RS232 adapters just to move a few feet further. All I wanted was to stop crawling under tables like a gremlin.

But, hey, after way too much fumbling, I found something that doesn’t need a ten-page manual or some arcane incantation. Ended up trying out this COM port redirector app, and shockingly, it kind of just… worked? No, really. Set it up, fed it the IP, and boom—talking to remote serial gear like it’s plugged in right beside me.

Real Talk: Why Even Bother?

  • No more spaghetti wiring: Say goodbye to PVC snakes behind your rack.
  • Quick setup: Felt like plugging in a toaster. Not even kidding.
  • Doesn’t make everything grind to a halt: Some of these things slow your system to a crawl, but this one’s like background noise—there, but outta the way.

If You’re Skeptical (Because I Am)

For those rolling their eyes, thinking “another software that promises too much,” I get it. I was literally expecting it to crash the first time I piped data through. But after a week—no mysterious disconnects. Maybe my luck, maybe good code.

So yeah, if you’re looking to access serial ports on devices you can’t just reach out and poke, maybe check this one out? No sponsorships, no weird popups. Just a tool that actually stays out of your hair.

Not to rain on @mikeappsreviewer’s parade (glad that tool worked for you!), but I’ll throw another perspective into the mix. The “set it and forget it” redirectors are cool until you try to pass anything beyond basic serial data—suddenly, stuff starts glitching or lagging like an old dial-up modem. Been burned after a “seamless” setup more times than I care to admit, especially when the tool flips out if you have a barrage of devices all going at once.

If you’re looking for a reliable solution to connect local and network serial ports—avoiding your gear acting like it’s haunted—take a look at Serial to Ethernet Connector. It’s built from the ground up for Windows, which means you get actual stability and not just another repackaged open-source tool disguising itself as enterprise software (we see you, shady free apps).

Does it cost a bit? Yeah, but you get granular control over port mapping, stable connections, encrypted traffic if you want, and zero drama if you need to run it as a service on boot. Useful if you’re running setups where uptime actually means something (think: industrial gear, POS stations, lab equipment, whatever).

I’d recommend checking out seamless remote serial port communication—you can trial it before buying, which is more than you get with half the freeware clutter. Plus, way less hair-pulling and swearing under your breath. Somebody put this thing through QA, finally.

Bottom line: if you already tried free, glitchy apps and need “it just works,” skip the cable acrobatics and give this a spin. If all you need is basic, maybe get by with @mikeappsreviewer’s solution, but for pro or industrial use, go with something actually designed for the task.

Not to rain with another suggestion after the detailed breakdowns from @mikeappsreviewer and @sternenwanderer, but let me throw in a pinch of skepticism and hope it helps somebody out. I spent way too much time playing whack-a-mole with free* COM port redirectors—think random disconnects, sketchy UIs stuck in 2003, and features that disappear just when you need them (seriously, one app gave out after I dared to connect two devices at once).

To be blunt, if you’re doing anything where uptime and reliability matter, I wouldn’t bet the farm on “no-brand” freeware, especially if remote serial device comms are what your workflow lives or dies by. You probably want something tested, built for Windows, and not repackaged OSS duct-taped together by someone who vanished off GitHub in 2018.

Serial to Ethernet Connector keeps popping up for good reason. Real dedicated COM port mapping, decent encryption, and it’ll run as a Windows service from boot—this stuff makes a BIG difference once you’ve tripped over enough cables or rebooted once too often. Yeah, it ain’t free (cue the collective sigh), but sometimes you gotta pay up front to avoid paying in headaches later. Heck, they offer a no-hassle trial, so no wallet risk to see if your ghosts-in-the-machine calm down.

If you want to sidestep the endless loop of uninstalling yet another broken tool, give this a shot: start connecting remote serial devices smoothly. Don’t let your setup turn into a haunted house of dropped connections and phantom errors. And if you do like open-source, knock yourself out with the options above, but don’t say no one warned ya when things break under load.

Anyway, would love to hear if anyone’s found a magic bullet solution. Or maybe serial-over-IP is just doomed to be 2020s cable spaghetti.

Alright, let’s cut straight to the chase—there’s a reason Serial to Ethernet Connector gets mentioned in threads like this, and it’s not just paid hype. After burning myself on a few of those janky free redirectors (yep, the ones that look like a Windows 98 science fair project), I needed reliability without the constant fear of BSODs or waking up to “Device Not Found” errors.

Serial to Ethernet Connector plays in a different league than the run-of-the-mill options—real virtual COM creation, robust encryption, works as a Windows service (so it reconnects and runs post-reboot), and genuinely solid remote access. No, it’s not free, but you get actual support and regular updates. Major plus: easy to map out multiple serial ports and not sweat over conflicts, unlike some contenders in this thread.

Pros:

  • Feels pro-grade (actually coded with intent for ongoing use, not just a one-shot tool).
  • Handles connections at scale—multi-port setups, headless systems, whatever you throw at it.
  • Windows service support is a lifesaver for unattended uptime.

Cons:

  • License cost might sting, especially if you’re used to freeware.
  • The interface is a little utilitarian—less shiny, more business.

Now, call me fussy, but I’m not 100% sold on any software being perfect. I’ve tried alternatives like what’s been shared by others (some usable, some not so much). The apps that promise a wizard-in-a-box install may occasionally work for quick & dirty lab tasks, but for ongoing, mission-critical serial routing? Pay for stability, save yourself repeated headaches.

In summary: if you’re tired of spiritual warfare with debug logs and losing serial devices in the network void, go with Serial to Ethernet Connector. It’s not magic, but it works. If your needs are super casual and money’s tight, sure, experiment with the other freeware/apps mentioned above—but don’t say you weren’t warned if they ghost you six months down the road.
