Connection

Mode

  • Built-in Terminal This serial port will be connected to UTM’s built in Terminal which can be configured in the proceeding section.
  • TCP Client Connection A TCP connection will be opened and if successful, the serial port will read and write to that socket.
  • TCP Server Connection A new socket is opened and the serial port will be connected to it. A client can connect to it in order to read and write to the serial port.
  • macOS Pseudo-TTY Device A PTTY device is created and the serial port is redirected to it. Another application can open the device and communicate with the VM. When this option is used, the PTTY device created will be listed in the VM’s details on the main window after the VM is started.

Target

  • Automatic QEMU provides routing for up to four serial devices automatically. The rules differ for each architecture and system target but they typically map to the main serial ports of the system.
  • Manual A new serial device can be created in the proceeding section.
  • GDB Debug Stub A gdbserver stub provided by QEMU can be mapped to the connection.
  • QEMU Monitor The QEMU monitor (HMP) can be mapped to the connection.

Wait for Connection
