Yes, serial ports are still used. They are most commonly used in industrial and scientific settings, where they are used to connect devices such as sensors and instruments. Serial ports are also used in some gaming consoles.
RS-232 is a standard for serial data communication while RS-485 is a standard for serial data communication over balanced lines. The main difference between RS-232 and RS-485 is that RS-232 uses voltage levels to represent binary data while RS-485 uses current levels.
A COM (communications port) is a port that is used to connect devices that use serial communication. Serial communication is a method of transmitting data one bit at a time. COM ports are used to connect devices such as modems, mice, and printers. To install a COM port, you will need to connect the device to the COM port using a serial cable. Once the device is connected, you will need to install drivers for the device. Drivers are software that allows the device to communicate with the operating system. Once the drivers are installed, you will need to configure
You can use a USB port as a COM port by using a USB-to-serial converter. This will allow you to connect your USB device to a serial port on your computer. You will need to install the driver for the converter on your computer.

On a desktop PC running Windows 10 with a low profile, I have 3 of these installed. The installation process was quick and simple, and the card was recognized right away. There were no problems when I added 2 more cards. No issues. I currently have 12 ports plus 1 built-in port.The port numbers on this particular PC have gaps because I previously had USB-based connections. I had to navigate to the serial ports in device management and select "display all devices." This will display any devices that have been defined but are currently absent. Renumber after removing them. All of the ports are now operational. I have tags on each port just in case.Although serial ports are no longer commonly found on PCs, I still have a room full of equipment that makes use of them. All of my GPSDO—please Google this term up—are currently connected to a PC for monitoring and, when necessary, testing. I've tried USB-based ports as well, but some of them unexpectedly changed their names, which was quite confusing. Although it costs extra, this card provides faultless performance.I was born when the PC-XT was brand-new. Serial ports are straightforward, but setting up numerous of them might be difficult. Cheap ones might function, but occasionally the drivers are dubious. Don't mix brands either. I therefore decided to stick with well-known brand names. I made the right choice (this one).

I have a Windows 7 PC with my card installed, and I use it to connect to and power a Garmin 18x LVC GPS Navigator Unit.The PEX1S553LP can be set to supply either 5 or 12 volts (or none) on pin 9 of the RS-232 DB-9 connector to power this serial GPS unit, which needs 5 volts (90 mA). The onboard Molex power connector can be used to supply power to the system power source. Jumpers can be used to configure each power choice. The card itself is Plug-n-Play, and the PC BIOS assigns the IRQ and I/O address automatically. The card has both low profile brackets and full profile brackets.The PEX1S553LP has PCI Express x 1 (version 1.0a) specs and a Moschip MCS9922CV-AA chipset (which supports up to 460.8 Kbps serial). Also installed in the Debian Linux machine is the StarTech.com 1 Port PCI RS232 Powered Serial Adapter Card (PCI1S650PW), which uses the GPS device as a time source for NTP. When necessary, the Windows 7 PC is solely utilized to upgrade the GPS's firmware because these tasks cannot be completed under Linux.By the way, the driver for this card is not installed automatically by Windows 7; you must download the most recent version from the Startech.com website.

To use with my brand-new Dell Inspiron 3000 PC running Windows 8.1, I first bought the Gearhead USB to serial converter from a nearby computer shop. Big error! I should have first read the Amazon reviews. The Gearhead unit came with a driver CD, and it was advertised as being compatible with Windows 8 on the box. Wrong. Driver loaded with a Windows warning about inadequate virtual memory in Device Manager. Anyhow, I was unable to make it work. went back to the shop. I ordered the StarTech adaptor from Amazon because it is known to function with Windows 8 and has been endorsed by Amazon users. As soon as it arrived, I put the USB end into my Dell, and sure enough, Windows found the driver on its own via Windows Update. Not even the driver from disk needed to be loaded. My Dylos Laser Particle Counter, which only has a serial interface, worked flawlessly. Currently, a PC is plotting particle counts. When checking counts in real time from the pretty large particle counter and needing to set the laptop down someplace nearby, the six foot cord with Startech converter is essential.

I purchased this to utilize on a client's computer that is running very outdated legacy software and printers. The absence of a low profile bracket is the only thing I have to complain about. It became my second choice for an adaptor card because it lacked the low profile bracket. My original choice, a "competitor product," failed a few days after installation, so I ended up getting this adapter card. Thankfully, the competitors' bracket fit on this card wonderfully. Installing and configuring this card was a breeze for me. The fact that my customer can continue to utilize their existing printers is the finest part. This was set up on a fresh Win7 32x machine with all the most recent updates applied. Great adaptor card performance

The 9 pin serial port is no longer present in modern computers, which still cost over $1,000! I tell you, GONE! UNITE, RS232 lovers! Save our ports, please! builds picket signs and enters the capitol in a march.I periodically work from home and need to evaluate embedded system programming. This was a total success. I just had one problem, which cost me a star: the setup process was quite difficult to understand. With Windows, I've learned to keep pressing "go" and not waste time reading. I had to press the same message seven times in a dialog box. I would have felt a lot more at ease if the text had been modified. When I thought I would be stuck in an infinite cycle, it abruptly stopped and finished installing on my Windows XP PC. Therefore, if you purchase this, simply keep pressing OK even though it appears that the program is performing the same action repeatedly. NOTE: You may need to MANUALLY switch your COM port to the lower numbers if you're using older software that can only access COM1-4 (pre-USB software). Keep in mind your reassignments. (Happily for those who recall the DOS redirect command!) We are unable to use the DOS redirect command either.

Since you utilize a serial port to log into your main networking equipment, having one accessible is crucial if you operate in the networking industry. It is now uncommon to find a good laptop that has a native serial connection built in since as computers have become thinner and lighter over time, the fairly hefty serial ports have been completely eliminated. The most popular way to get a COM port is to purchase USB-to-Serial adapters, sometimes known as dongles. Despite the fact that these dongles are quite effective, with repeated usage and gradual wear and tear they begin to lose their efficiency and must finally be replaced entirely. This is especially true if you continually disconnecting and reconnecting them. I have tried both inexpensive and more costly dongles, but ultimately either the dongle or the Rollover cable needs to be replaced. Therefore, I made the decision to try something new this time and purchased this Startech Expresscard RS232 Serial Adapter.I must admit that this device performs admirably, and since I don't intend to take out the ExpressCard anytime soon, I don't anticipate experiencing the same wear and tear problems as I had with the dongles. On your computer, this device will produce a virtual COM port that will enable trouble-free console access to your networking hardware. I don't have to worry about the length of the cables that came from the dongles because it behaves more like a native serial port, and all of my USB ports are now available for use. It really is a fantastic product, however owing to some initial installation troubles, I have to take one star off of my rating.The Serial Adapter Card's user interface is not very good. As another reviewer noted, the ExpressCard will attempt to automatically install the device's drivers as soon as you insert it into the slot. Unavoidably, it will fail, requiring you to manually install the driver. To my dismay, manually installing the drivers turned out to be difficult. I received Code 10 "This device cannot start" warnings because neither the drivers offered on the small disc nor the drivers offered on Startech's website would correctly install. Reinstalling the drivers and restarting the computer did not fix the problem. When I finally called Startech help, we discovered that installing the outdated legacy driver was the only way to get the driver to function on my laptop (a Dell Latitude E6420).Other than the difficulties setting up the driver, this device works fantastically and I heartily recommend it to anyone seeking for a more reliable alternative to dongles.
A serial port sends data one bit at a time, in sequential order. The data is sent over a single wire, making it easy to connect to devices.
A serial port is a computer interface used for connecting peripherals, most often using a serial cable. The speed of a serial port is measured in baud rate, or bits per second (bps). The standard speed for a serial port is 115200 bps, but some serial ports can operate at speeds up to 12 Mbps.
A USB (Universal Serial Bus) is a standard for connecting computer peripherals. It is not a serial port.
PCIe is a serial port, but it is not the only serial port. There are other serial ports that are used for different purposes.
