GearmoUSB-C to RS-232 Serial Adapter, FTDI Chip, LED Indicators, High-Speed Data Transfer, Cross-Platform Compatible

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.

Because it came fully wired it saves time for the user. Especially that user who doesn’t know how to wire one.

Provides a needed com port.

didnt function and screws were wrong

This USB-C to serial adaptor worked perfectly on my Mac OS Mojave. No drivers needed. Used the very basic but functional "screen" command from the terminal App and was able to console into various Cisco gear like a champ. Lights for the pins are nice feedback for the serial comms. Excellent tool.

After using two weeks it’s good

I bought it with an indication because activity control was important to me. It’s better to pay extra and buy Cisco.

This product works as advertised but I wish the Type C connector was more robust. The male metal element, that is inserted into a type C slot, is not well attached the the rest of the housing. It has always been a little bit loose but I needed the converter so I put it into service.
