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…?

A Lot of Product for a Good Price

Updated: Finally, a good app at a good price to control serial device connections with my MAC. In addition, this app allows you to view the Hex/ascii if you choose, which would be good if you’re doing serial programming. “The backspace key on my MAC is a delete key, and the delete key does not “yet” delete input with this app. I’m bringing to 4 stars because while I can restart a line by pressing "Ctrl + C”; I found since I am not a perfect typer, I could use the backspace/delete ability. I’m sure I haven’t located the correct key combination or something. It could be my device, but if the backspace/delete character and up/down arrow command recall is fixed, 5 stars all the way. Still Super: No more running “Screen” and looking up the device name to create a serial connection. No more having to kill the process to restart “Screen” at the command line if I want to change baud. Great product at a great price. I have other expensive products, but they are licensed for other devices. I love the App Store products because you can use purchases on all your devices; if there is a limit, I have not reached it. Could you contact me when my minor issue is fixed so I may boost the rating back to 5 stars? *****

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.
