Trying to connect a device with a serial port to my local network so I can access it remotely over IP. Not sure what hardware or software I need, or how to set it up. Has anyone done this before or can recommend a solution that works for serial-to-IP communication?
Tested a Bunch―Only This “Serial Over IP” Worked out of the Box
Look, I’ve crashed more apps than I’ve actually finished setting up, so when I say a tool is easy, it means my coffee didn’t get cold mid-setup. The one I didn’t end up cursing at is this: serial over IP solution. Seriously, I’ve wasted evenings wrestling with configs and random drivers just to get a serial port talking across my network, but this one didn’t make me dig into a support forum even once. No mystical sacrifices to the driver gods, no arcane error popups, just, boom, working.
Eh, What’s The Real Difference?
Honestly, I’ve spun up half a dozen “virtual COM port” tricks, and 90% of them sneak in some weird limitation or want a license key from the 90s. This one? Legit just worked. Clicked through setup, and my random old barcode scanner started piping data from my garage PC to the living room. Didn’t have to mess with firewall rules, didn’t nuke my IP stack, nothing. That counts as a win.
Story Time: My Other Serial Over IP Failures
Before you go thinking I’m some glowing fanboy, let me put it this way: last time I tried another tool, my device manager ended up with more yellow triangles than an Ikea sale. Then the laptop crashed because the software tried to “optimize port latency.” I knew optimism was dangerous.
TL;DR
If you’re like me—tired, impatient, beefing with USB-to-serial ghosts—use this tool. Seriously, it’s actual plug and play. And I don’t say that lightly.

Real talk: sometimes software really is the easiest path, but there’s still plenty of other ways to get serial port data across your local network—especially if you don’t want to rely on a single tool or you need something “meatier” for enterprise setups. I get @mikeappsreviewer’s pain with some of those “virtual COM port” apps (rage-quit time, anyone?), but I actually ended up going a totally different route in my last project.
First, those dedicated hardware boxes—aka ‘serial device servers’ or ‘serial-to-Ethernet converters’—are clutch when you want reliability and don’t trust software shims not to nuke your stack. Drop one next to your serial device, ethernet to your LAN, config in a browser, boom, instant network port. Brands like Lantronix or Digi are solid, but not exactly wallet-friendly for hobby projects.
For software-only approaches, I’d check out Serial to Ethernet Connector. It’s basically like what @mikeappsreviewer is hyped about, but with a few unique features. It lets you create virtual COM ports on any computer on your network, connects real serial devices over IP (TCP or UDP!), and supports Windows and Linux. I found it way more customizable if you ever need to forward multiple serial connections, or run things headless. You can learn more with this jam-packed page: Effortlessly Share Serial Devices Over Network.
Honestly, the setup still isn’t totally idiot-proof—sometimes you run into “port already in use” errors or firewall gotchas if you’re juggling lots of devices. But atleast you’re not installing sketch drivers from a zip file you found on a pastebin, so that’s a win.
Last hot take: don’t sleep on just using a Pi or old thin client as a “serial bridge” if you’re already knee-deep in the DIY world. USB-RS232 adapter, some socat or ser2net, couple bash lines, and you get flexible forwarding without locking yourself into someone’s GUI forever.
So, yeah, plenty of options: hardware boxes if you want bulletproof, software like Serial to Ethernet Connector if you want quick(ish) and flexible, or roll-your-own if you enjoy pain. If you want pure plug-and-pray, the link above worked for me better than most. Otherwise, happy to walk you through some CLI configs if you want to go full nerd.
Not gonna lie, the whole “serial over IP” journey is usually one of those choose-your-own-adventure headaches—so I’ll save you the pain. @mikeappsreviewer and @shizuka both nailed a lot: plug-and-play apps exist (yeah, miracles happen), hardware boxes are rock solid but pricy, software is a mixed bag, and there’s always the “throw a Pi at it” hack.
But hey, don’t sleep on some old-school, open solutions if you’re not allergic to the CLI. For Linux folks (or if you’ve got a stubborn Windows box willing to run Cygwin), try ser2net or socat. They’re free, trivial to run, don’t need sketchy drivers, and let you map serial devices to TCP ports with a couple lines in config. Downside? Not as pretty, sometimes fiddly, and security is basically “not our problem,” but you get total control. If you’re the tinker type, that can be a win.
Quick comparo to the ZXCVB “install me and forget it” flavor apps: sure, those work, but you’re married to their ecosystem and support desk. Personally, I want stuff that survives when the vendor nukes their download pages in five years. That said, if you want a balance of plug-and-play and power, Serial to Ethernet Connector is honestly unmatched for that middle ground—virtual COM ports all over your network, supports a bunch of OSes, and handles multiple sessions without choking. You don’t have to sell your firstborn to ebay to buy one of those hardware bricks, either.
So ignoring all the “it just works” hype, here’s how I’d do it:
TL;DR List-O-Matic:
- Need simple, fast, and easy? Grab an app like Serial to Ethernet Connector and check out their guide for remote serial access.
- Want total control, or doing DIY? Use ser2net, socat, or dig into Pi-based solutions.
- Bank vault reliability? Shrug and drop some dough on a Lantronix or Digi device server. They work, but will haunt your budget.
- Avoid:
- “Random free virtual COM apps” that haven’t been updated since XP
- Drivers labeled “beta,” unless you like bluescreens
The best route honestly depends on how much you trust software, how much you want to spend, and whether your goal is “out of the box” or “I control every bit.” Oh, and for what it’s worth, the step-by-step for Serial to Ethernet Connector is right here, makes the whole remote serial to IP process dead simple.
Just don’t say nobody warned you about the yellow triangles.
