What USB-RS232 adaptors do y’all use and would it make any difference?
This is the "famous" Keyspan: https://www.amazon.com/Tripp-Lite-Keyspan-High-Speed-USA-19HS/dp/B0000VYJRY/ It uses a Texas Instruments chipset and is very stable, and works like a champ. This is the less famous IOGear GUC232A: https://www.amazon.com/IOGEAR-Serial-RS-232-Adapter-GUC232A/dp/B000067VB7/ It uses a Prolific PL-2303HXC chipset, and is roughly half the cost of the Keyspan. The Prolific chipset devices tend to change COM ports when they feel like it and have a somewhat negative reputation largely caused by low-quality counterfit devices. I've been using one of these IOGear units for years. Someday when it dies, or if I need to move to USB-C, I'll probably upgrade to the Keyspan (which is available in a USB-C version). It doesn't really matter, so long as you buy an authentic product that is well manufactured. More on reddit.com

Serial communication is not working. Is the problem caused by the adapter or my serial software application?
Older applications that use serial communication often use legacy hardware addresses that do not work with PCI, PCIe, or USB to Serial products. We recommend contacting the software provider/support team to check if this is the case.

How can I make sure my serial port is working in Windows?
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: https://www.startech.com/faq/com-port-listing-windows .

r/Cisco on Reddit: What USB-RS232 adaptors do y’all use and would it make any difference?
September 19, 2023 - I've got a uPort 1250 and IMHO it's almost as good as a physical serial port. ... Only name-brands and only FTDI chipsets. There is no amount of money you can save on a console cable that makes a cheap one worth it. Today, you can find plenty of direct USB-rollover cables, and if Cisco X2 are the only connections you need, these can keep your bag much cleaner.
