Hello, The Problem: A friend of mine has some win32 and msdos applications that use serial port communication with an external device, and a notebook that doesn't have a serial port unfortunately, many notebooks these days come without serial ports. I'm trying to find out a solution to use them under ms-dos. Joined Oct 8, Messages Scour the internet, I believe I saw one out there.

If you want to confirm the port change has indeed been made, click on Device Manager again and check the listed Ports.
Now close the System Properties window. At this point, you are ready to use the virtual COM port in any application! Note that, if you unplug the USB device and plug it back in later, Windows will still remember the COM port assignment, so you won't need to go through this procedure again.
It lets you add another serial port to any USB-compatible Windows computer in about a minute, without taking up any extra system resources or requiring you to open the computer up, or even reboot. In the Converter's box there's the gizmo itself, a simple brochure-manual that tells you all you need to know about getting it running, a floppy disk and a warranty card.
Notably, and inexplicably, there's no USB cable included, so you'll have to add the price of a standard A-to-B cable the A connector is the flatter one to the Converter's cost.
The Converter gives you a standard male 25 pin D connector, which means you can plug it straight into the back of most modems, but will need a to-9 pin adapter to connect it to the many other devices that use the smaller connector. The Converter's driver floppy disk contains software for both Windows 95 and On my Win98 system, installation was a doddle; plug the Converter in, feed the computer the floppy disk, tell the Add New Hardware Wizard where the drivers were, sit back and watch for a moment.
No rebooting, no fiddling, and hey presto - a new serial port in the Device List:. The new port behaves very much like the standard ones, with a couple of differences. Of course, it uses no resources, but it also differs from standard COM ports in that it's not automatically visible to DOS programs, even when you run them from inside Windows.
I'm not a computer guy but I believe they are out there so the gamers can play their legacy DOS games. I don't have any idea if it would work with your software though.
I don't remember what they cost but they are fairly cheap, I've used them for a few years at one place, and we even have a few on the shelf in the box as backups. Windows run in DOS. Windows is the user friendly face of DOS. You just need to bring up the DOS command prompt. But be careful. The failsafe protections of Windows is not available in the DOS window.

The newer machines will kill you with issues such as too high processor speeds, chipset issues, etc. Modern processors are 32 bit and higher.
