Works Great for EdgeRouter Serial Console under High Sierra
There are some over-priced software products out there for using your USB port to access the serial console on a Router, but this one was Free and does a very nice job. I had a new Router that needed to have new Firmware flashed before the web interface would be effective and I was able to connect to the Serial Console immediately after setting the proper speed setting in the software. (I used a US$10 cable from an online store.)
I am very pleased with this products and after a day of extensive Connect, Disconnect, Exit, Launch, Connect, Disconnect (rince and repeat) I had no issues with this software at all. I’m really not sure what the source of the poor ratings is, but I had no such experience with a Late-2013 Mac Pro and an FTDI USB-RJ45 serial cable.
Decent serial I/O app...
This application is free and provides the essentials for connecting your Mac to a remote device etc. via serial communication link. In fact it works better than most of the other for pay serial monitor apps in the Mac store. In my case I was using a CDC driver for serial communication over USB to connect to the UART of a development board. The driver appeared in the drop down list as expected and this application connected with and displayed all of the strings coming out of the UART while the target application was running. Definitely worth taking a look at this application and well worth the price (free!). Thanks for taking the time to develop it and making it available for free.
this app used to work well under older versions of OSX but the latest version from 2015 has probems with Sierra, it sees the USB serial ports but I can’t send/receive data & it crashes on disconnect. I know the serial dongles still work with other (older!) apps under Sierra, so…?
With Family Sharing set up, up to six family members can use this app.
