It’s written by David Alverson and is free to use, though he’ll happily accept donations if you’ve found Z-Term useful. Installing Z-Term, a terminal emulator application that I’ve been using to hook up Macs remotely since the late 1980s, is easy too. I bought my cable from Farnell, by the way - it terminates in three female connectors ready to slot onto the Pi’s GPIO pins.ĭownloading and installing FTDI’s drivers is the work of a moment.
The Pi hooks its UART pins to a login console at boot, and it should be straightforward with a suitable USB-Serial adaptor - I have the TTL-232R-3V3 from FTDI Chip - to view the results of the start-up process on a terminal window in Mac OS X. The Pi has 26 general purpose IO ports on board, two of which can be used for UART (Universal Asynchronous Receivers/Transmitters) communications.
