USB-C 2.0 to Serial RS-232 Adapter w/ LED Indicators

Product Review (submitted on June 2, 2023):

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.
