June 7, 2025What 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

September 19, 2023Which USB-RS232 adapter to get?
I’ve used various cables with FTDI chips pretty successfully. My last one was a cheap AliExpress/eBay cable, but I can’t find it anymore so can’t point you in the right direction. 🤷♂️ More on reddit.com

USB-C to RS-232 (DB9) Adapter Cable: Pinout, Wiring, and Grounding Guide | Romtronic
August 29, 2025 - (Some routers/Cisco consoles use a female DB9, some use RJ45 rolled cables.) Baud rate mismatches: Verify that both devices use the same baud, parity, and flow control. Many adapters auto-negotiate or include LEDs, allowing you to see TX/RX pulses. Ground loops or noise: If data is garbled, try grounding the cable shield as described above. In extreme cases, use an isolated USB‑serial adapter or RS-422 converter.
