Perfectly Serial Terminal
I've been using this app for several years to interface with serial ports of many different embedded devices. It has become an essential tool for firmware development and am very happy that it continues to be updated. It's one of the few apps I'm never looking out to replace. — Ana70g
The best serial port tool I’ve used. — keith_duncan
Seriously, still the best terminal emulator ,,,
... on any platform. Better than Br@y's terminal or TeraTerm on Windows. Better than screen on the command line. What's great about it is that it has drivers for all sorts of USB-to-serial devices, even some for which no macOS driver exists. — AP in Tucson
