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. I have other expensive products, but they are licensed for other devices. No more having to kill the process to restart “Screen” at the command line if I want to change baud. Still Super: No more running “Screen” and looking up the device name to create a serial connection. It could be my device, but if the backspace/delete character and up/down arrow command recall is fixed, 5 stars all the way. I’m sure I haven’t located the correct key combination or something. 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. “The backspace key on my MAC is a delete key, and the delete key does not “yet” delete input with this app. In addition, this app allows you to view the Hex/ascii if you choose, which would be good if you’re doing serial programming.

Updated: Finally, a good app at a good price to control serial device connections with my MAC. Macs are excellent tools for accessing serial device TTY ports (to console.
