You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.

For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.
Easily add an RS-232 9-pin serial port to any computer with our PL2303-DB9 USB to Serial Adapter!This adapter will let you connect older serial devices to modern computers, for terminal services, data transferring, remote control, and programming. Supports baud rates from 75bps to 12Mbps, multiple stop bit and parity types.
Plugable's USB to Serial Adapter features Prolific's PL-2303HX Rev D chip for the best combination of support and performance with a wide range of RS-232 serial devices. Drivers are built-into Windows 11, 10, 8.x, 7, and most Linux distributions, drivers are available for Windows XP, Vista, and macOS.
This adapter replaces a legacy built-in or PCI serial port and features a fixed male port with screw in connection. For connecting devices that also have a male connector an inexpensive DB9 coupler or standard serial cable can be purchased separately.
Works with devices with RS-232 serial ports such as other PCs with RS-232 ports, Bluetooth serial adapters, telescopes, amateur radio gear, GPS receivers, routers, firewalls, modems, plotters, embedded character displays, scan tools, sonar units, embedded boards and many others. Specific devices include: Garmin eTrex GPS, Seiko Label Printer, iRobot Create, Cisco products with serial consoles, US Robotics Modems, NexStar telescopes, Equus Scan Tools, Uniden Hand Held Scanners, etc. Works with software like: HyperTerminal, TeraTerm, WinDBG, all open source serial software on Linux, etc.
We use only genuine Prolific serial chipsets in our adapter. Some inexpensive serial adapters use cloned Prolific serial chipsets that will not work with the latest Prolific drivers, both those available for download and the drivers embedded in Windows. Because we only use genuine Prolific chips, our adapter is always compatible with the latest drivers from Prolific.
Following the installation instructions provided by the manufacturer of your serial devices, install any needed software or drivers. Connect the serial device to the adapter, and make any needed settings, such as COM port, baud rate, flow control, stop bits, etc.
The Plugable USB serial adapter allows you to connect legacy devices that use RS232 serial communications to computers that do not have a serial port. Although this usually works well, a number of problems can crop up because many of the devices people want to connect are older devices with various issues. A frequent problem is that the software that is necessary to connect to the device does not work under modern operating systems such as Windows 7 or above. Other problems can include using an improper cable, incorrect port settings, or a basic incompatibility between the Plugable USB serial adapter and the device it is being connected to.
When the cable is plugged into Windows 7 or higher computers, the necessary driver should load automatically. If it does not load, make sure the computer is connected to the internet. If an internet connection is not available, download the latest drivers for the cable from the Plugable driver site here. For earlier Windows XP and Vista computers, the drivers must be downloaded from the Plugable website and installed.
In Windows, serial communications proceed through a COM port that is assigned by Windows when the USB serial adapter is plugged in. You can find out this COM port by opening Device Manager, going to Ports (COM & LTPT) and looking for Prolific USB-to_Serial Comm Port (COM#). The # symbol represents the port number of the COM port assigned by Windows. This port must be set correctly in whatever application is trying to communicate through that port.
For USB to RS-232 chips, there are two primary manufacturers: Prolific and FTDI. Because off-brand chips with poor drivers are unreliable, Campbell Scientific recommends and currently sells a cable using an FTDI chip (part number 17394). We chose this cable because it uses a chip that has a certified driver available on Windows Update. (The older cables were silver in color and did not have a driver available for Windows beyond version 7.)
We have a couple older CNC machines that use rs232. The onboard storage is very small so they will request the file in chunks from the host PC. I want to update there computers but with phasing out of serial ports, my best option is a USB to serial adapter. Is this a viable option for machines that require this connection to run for hours at a time?
I have an issue where my prolific USB to Serial adapter stopped being detected as 'n "Ports (Com & LPT)" device. It keeps on detecting it is a " USB Composite" device, even after installing the correct Windows drivers downloaded directly from the manufacturer's website. Uninstalling it and reinstalling it doesn't help.
I get the same result on another computer also running Windows 10. It simply refuses to recognize the adapter as a USB to Serial device anymore and keeps on detecting it as a "USB Composite" device as soon as you plug it in after uninstalling it and restarting Windows. Windows also claims that it finds no better driver than the one currently installed when doing a driver search, even after installing the manufacturer drivers.
Our USB to Serial Adapter fully supports Windows 11, Windows 10, Windows 8, Windows 7. Utilizing the Newest FTDI Chip Technology allowing to be upwards compatible with Newer Operating Systems. Replacing your old USB to Serial Adapter with our new USB to serial adapter should be completely seamless. You can plug our adapter in and click update drivers from Windows and it will automatically download the drivers directly from Microsoft. The Drivers are fully certified.

Installing the wrong driver, or simply an incompatible version of the right driver, can make your problems even worse.
I will be moving from PC to Mac, but will need to run a Windows application that uses a serial port, using boot camp. Would I be right in thinking I would need to install this adapter under Windows using a Windows driver?
Hi Doug,If you have the Plugable adapter, the latest driver for OS X is properly signed and there is no need to turn off SIP in order to install it. If you are having problems getting it installed, please contact us at support@plugable.com and we can help.
David, thanks for the response, I should start at the beginning, I have an older Cables 2 Go USB2Serial cable and my research indicated that the driver I needed was this one. It works on a windows PC but since I use a MAC most of the time I was trying to get it to work. However, I have since ordered a plugable adapter and I think it should be here today and I am sure that will solve my problem. I will keep you posted.
