desertcart.com: Gearmo USB C to RS232 Serial Adapter FTDI Chip LED Indicators High Speed Data Transfer Cross Platform Compatible 3 ft Cable : Electronics

Review: Very well functioning USB-Serial Converter - This is a very well functioning USB-RS232 serial converter. After trying (and failing) using a well-reviewed Keyspan converter that I've had for several years (with TI chip and Keyspan driver), I tried this Gearmo with the FTDI chip and have had excellent results on an Intel Mac Mini with MacOS 10.14.6 (Mojave) with the stock FTDI driver that comes with MacOS. My application is using a remote serial console communicating with the getty daemon that MacOS also includes. I use RTS/CTS hardware handshaking at 19,200 baud and up, and haven't experienced any issues. The FTDI chip and the Apple driver appear to respect all the termios serial flags and commands used by the appropriate gettytab file entry (I had to modify my gettytab entry for the settings I used -- that takes a little work, but once you understand all the flags it's not bad). Finally, I like having the LEDs for the various serial lines. The Gearmo is a nice little product at a great price.
Review: Works perfectly, no additional drivers needed - Worked (almost*) right out of the box. Tested only in Windows 10 64 bit. Needed to program a universal remote (URC MX-800, also should work with all other variants like MX-600, MX-700, etc). *The default latency was set to 16ms which made it not communicate with my equipment properly, but setting it to 1ms in device manager solved it. LED's are nice and useful, you can see which lanes/pins are actively receiving or transmitting. Material of the case is good. Two things that could make this even more perfect in my humble opinion. Make the cable the same color as the case (smoke colored). As it is, it looks like something from 2003 or so with its see-through cable and being able to see the sheilding. Second, if they could somehow add a opaque piece of plastic between each LED so the light doesnt bleed into the holes next to it, it would look so much more nice looking and easier to read the LEDs.

### ⭐⭐⭐⭐⭐ Best plug and play RS232 adapter
*by H***K on October 15, 2023*

I use them with older instrumentation software. They work flawlessly. The LED lights are a great communication check. They work on old PCs and new ones. All types of software and hardware. They work with VMWare Virtual computers or directly. They are better and more compatible than the add in cards. They are better, less flaky than other USB adapters I've tried. The are supported in all versions of Windows with or without the included driver CD. I wouldn't buy any other USB RS232 adapter.
