Virtual COM Port Driver emulates virtual serial ports and connects them in pairs via virtual null modem cable. Applications on both ends of the pair will be able to exchange data in such a way, that everything written to the first port will appear in the second one and backwards. All virtual COM ports work and behave exactly like real ones, emulating all their settings. You can create as many virtual port pairs as you want, so there will be no serial ports shortage and no additional hardware crowding your desk. Moreover, Eltima virtual serial port technology can be fully integrated into your own software (DLL, ActiveX or Core level usage).
In case your application is designed to work with a limited number of ports, you can use Switcher, a special feature of Virtual Serial Port Driver PRO. With this option, you can join several physical ports into one virtual (optionally, you can give the same name to all of the ports), and create a switcher to this virtual COM port in the required app. Whenever your program will require a serial port connection, the switcher will detect a non-occupied COM port in the list of joined ports and offer it to the app. This way, your program will automatically talk to any free serial port as though it were always the same port. Virtual ports, created by Serial Port Emulator utility, work exactly like real ones.
They emulate all real serial ports settings and provide strict baudrate emulation and full HandFlow control support. Additionally, you can easily emulate a serial line break (only for Standard License). Moreover, VSPD uses advanced Windows kernel driver technology, which ensures WDM, WMI, Power Management, PnP, etc. Virtual COM Port Driver is fully compatible with API COM and supports all Windows messages.
I am searching for a simple method to list all available com port on a PC. I have found this method but it is Windows-specific: Listing serial (COM) ports on Windows? I am using Python 3 with pySerial on a Windows 7 PC. Arduino Nano not visible in Serial Ports (Mac OS) Ask Question 4. But, the serial port doesn't still show up on my Arduino IDE when I connect my Wemos D1 mini chip (which uses CH340G chipset). – ram Sep 23 '17 at 8:39.
This USB-C™ to serial adapter lets you connect your USB-C devices to your legacy serial equipment. It converts a USB-C port on your laptop or computer into a RS232 DB9 serial port, giving you a cost-saving way to connect to serial devices such as point-of-sale terminals, serial modems, industrial equipment, and a wide variety of other RS232 peripherals. Connect with ease The RS232 adapter cable is compatible with Windows®, macOS and Linux® operating systems, which makes it easy to integrate into mixed environments. Ready for mobile or desktop applications The USB-C to serial adapter is USB powered, so you don’t need an additional external power supply. It’s a compact solution that’s easy to bring along with your laptop, when you’re on the go. The ICUSB232C is backed by a StarTech.com 2-year warranty and free lifetime technical support.
When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:. Serial cables. Serial ports. Serial devices To test your setup components, try the following:. Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup. Use a different serial cable, serial port, and serial device in your setup to see if the problem persists.
Ideally, you should test a component that you know works in another setup. When you test your cables, it is recommended that you do the following:. Test each cable individually. Use short cables when you are testing. When you test the serial ports and serial device, it is recommended that you do the following:.
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT). Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number. If you do not see the COM port number in Device Manager see this FAQ for PCI/PCIe expansion cards: or this FAQ for USB devices:. If the device is listed with an error, follow the instructions on the website to reinstall the drivers. Note: Some serial devices work only if the COM port number is between a certain range.

For example, COM1 to COM4. Perform a serial loopback test. See this FAQ on how to perform a RS-232 serial loopback test. To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:. If your serial port is not female, convert it by taking a female/female cable or gender changer and plugging it into the serial port. Take a metal paperclip or wire and cross pins 2 and 3. If you look closely at the female end, the pins should be numbered.
Open a telnet session on the COM port number of the device that you are testing. To find out the COM port number, refer to the following FAQ:. Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. Windows XP comes with Hyper Terminal.
When the session is open, anything you type into it you should see. The loopback test fails when you cannot see what you are typing. If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port.
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 products related to this article, click.
