Define a list of serial port(s) that you use regularly. Each entry defines a SerialDomain with the following fields:

• name - the name to use for the serial domain. Must be unique across all multiplexer domains in your configuration.
• port - the name of the serial device. On Windows systems this can be a name like COM0. On Posix systems this will be a device path something like /dev/ttyUSB0. If omitted, the name field be interpreted as the port name.
• baud - the communication speed to assign to the port. If omitted, the default baud rate will be 9600.

This configuration defines a single port:

config.serial_ports = {
  {
    name = '/dev/tty.usbserial-10',
    baud = 115200,
  },
}

You can then use the port in one of the following ways:

• wezterm connect /dev/tty.usbserial-10 - this behaves similarly to wezterm serial /dev/tty.usbserial-10 --baud 115200.
• Start wezterm normally, then use the Command Palette or Launcher Menu to spawn a new tab in the /dev/tty.usbserial-10 domain to connect to the serial device
• You can reference the serial domain by its name /dev/tty.usbserial-10 in the various tab/window spawning key assignments that include a SpawnCommand

You can define multiple ports if you require, and use friendly name for them:

config.serial_ports = {
  {
    name = 'Sensor 1',
    port = '/dev/tty.usbserial-10',
    baud = 115200,
  },
  {
    name = 'Sensor 2',
    port = '/dev/tty.usbserial-11',
    baud = 115200,
  },
}
