People ask a lot, so here’s the ZTerm settings that work well for me. The screen I skipped have no impact on what we’re usually doing. The last screenshot shows how to save the settings. Yes for some reason they put it on the Dial menu.
Be sure to pick the appropriate serial port. Holding down the shift key on the keyboard while the application is launching will display a prompt to choose the serial port.
The Mac OS is desperately in need of an open-source replacement for ZTerm, which hasn’t been updated in eight years. A friend of mine is working on a total new Macintosh serial program, so hopefully there can be an announcement about that in the near future.
