The command setserial -g ${device1 device2 ---} is used to retrieve and display the configuration and settings of one or multiple serial devices. Here is a breakdown of the different components:

• setserial: This is the command-line utility used to configure serial port settings in Linux.
• -g: This option is used to read the configuration of the specified serial device(s) and display them in a human-readable format.
• ${device1 device2 ---}: This is a placeholder for listing the serial device(s) you want to retrieve information for. The device names should be separated by spaces.

For example, if you want to retrieve information about two serial devices with names ttyS0 and ttyS1, you would replace ${device1 device2 ---} with ttyS0 ttyS1. The command would then be setserial -g ttyS0 ttyS1.

The output of the command will typically provide details about each serial device's settings, such as baud rate, data bits, stop bits, parity, and flow control.
