Serial console on Mac

What it’s for

Section titled “What it’s for”

Routers, switches, development boards (like ESP32 or Raspberry Pi), and anything else with a USB console cable — the serial console gives them the same native terminal as your SSH sessions.

Connecting

Section titled “Connecting”
  1. Plug in the USB serial device.
  2. Create a serial connection and pick the device, baud rate (for example 115200), and line settings.
  3. Open the session. Output appears in a regular terminal tab.

An ad-hoc serial connection can be saved as a profile, so a board you use daily is one click away.

Device reconnects

Section titled “Device reconnects”

If the device disappears (unplugged, board reset), the session stays open. When a matching device reappears, the session can resume automatically — see Serial device matching if the wrong device is picked up.
