I’m working on a project that depends on creating virtual serial ports for testing communication between two applications. I need an emulator app that is compatible with my development environment because the tools I tried so far haven’t worked. Any suggestions or advice about which software to use would really help.
So, let’s just drop the PR talk for a minute—I’ve played with a bunch of these virtual serial port tools, and honestly, your wallet and wishlist really drive the outcome. Case in point: this virtual serial ports emulator.
For the average user who wants to merge a couple of ports or split traffic between devices, you get what you show up for. Got a mess of GPS emulators, industrial sensors, and one stubborn old CNC machine? No problem.
Would I tell my boss to buy it if we needed maximum flexibility and zero nonsense? Yeah, probably. It just works quietly in the background and doesn’t bombard you with endless up-sell reminders or ads for other utilities.
If you’re looking to split or merge serial ports—either because some half-abandoned device in your lab refuses to cooperate, or you’re juggling too many connections for your comms analysis—this tool is honestly a solid bet.
Try it, or don’t, but it won’t let you down in regular use.

I see @mikeappsreviewer has already talked up some virtual port emulators (and yeah, most options either look ancient or just choke under more than two connections). But let’s be real—sometimes you need more than just a port splitter; you need legit flexibility, especially if your dev setup is picky (looking at you, weird microcontroller SDKs).
Personally, I’ve tried more than a few, but Virtual Serial Port Driver always ended up being my “set-and-forget” tool. It actually creates virtual COM port pairs, not just splits an existing one. If you’re doing two-app testing, stuff like echo, loopback, or port bridging is right there, and it’s much less crash-happy than some of the “freeware with open dialogs everywhere” apps out there.
One thing I disagree about: “it just works in the background.” Eh, kinda. It’s smooth most of the time, but every once in a while if you’re running custom baud rates or funky flow control configs, you’ll hit the occasional quirk. Nothing deal-breaking, but worth mentioning if your project is non-standard.
Want it quick? Forget jumping through hoops or popups. Just go to set up your virtual com ports right here. Super straightforward install, doesn’t try to force extra junk on your system.
Short version: Virtual Serial Port Driver is the one I keep coming back to for actual dev work—not just toying around. It’s definitely worth a look if you haven’t already banged your head against it. YMMV, but beats the “didn’t connect” error roulette I get with a lot of others.
Alright, quick hit list for anyone still weighing virtual serial port emulators:
Pros of Virtual Serial Port Driver:
- Actually creates true virtual COM port pairs, not just splits existing hardware.
- Super stable under heavy dev testing—doesn’t bomb with multiple apps or toolchains running.
- Slick install, no bundled junk, simple UI.
- Features like echo, loopback, port bridging are built-in (makes bidirectional testing painless).
Cons:
- Not free—if you’re just tinkering on a hobby project, the price tag might sting a bit.
- Occasionally weirds out with nonstandard flow or baud settings (a rare thing, but it’s there).
- Windows-only; if you dabble in Linux or macOS land, you’re out of luck.
Some folks love VSPD for complex test setups, some figure it’s overkill. I’ve been down the VSPE and Eltima routes—VSPE is ok for single pair quickies but starts coughing when stressed, while Eltima’s GUI feels like a time capsule (to put it nicely) and gets confusing with advanced configs.
If your workflow revolves around testing two apps talking over serial (and doesn’t need physical cables draped across your desk), “Virtual Serial Port Driver” really does streamline things. Minimal guesswork, keeps the dev cycle moving. Not flawless, but the quirks are manageable. Depending on your OS and how wild your comms scenarios get, it might just be the least annoying tool in the bunch.
