A native macOS serial terminal for firmware and hardware engineers. Plug in a board, pick the port, and read what it is actually saying — without wrestling with a terminal emulator first.
Not a terminal emulator with a serial mode bolted on — a tool that keeps a board, its settings and your notes together.
A project remembers the device and every port parameter. Open it tomorrow and the connection is already configured — no setup ritual before every debug session.
Group the connections a product needs — MCU, radio module, power board — each with its own settings and its own logged debug time.
Baud, data bits, parity, stop bits and flow control sit on one panel, not buried in dialogs. Toggle DTR and RTS while connected, send a Break, and watch the line state respond.
Data is rendered exactly as it arrives, in a monospaced font and size you choose. Switch to HEX when the bytes matter, add timestamps when the timing does. Send commands with a keyboard shortcut, pick the line ending, or repeat a message on an interval. Keep the register values and magic AT commands in the side notepad, in the same project.
No account, no cloud, no telemetry. Your serial data, projects and notes never leave your Mac.
