- Settings are stored in a structured text file making it easy for users and/or tools to configure. Using Terminal's configuration mechanism, you will be able to create multiple 'profiles' for each shell/app/tool you want to use, whether it be PowerShell, Command Prompt, Ubuntu, or even SSH connections to Azure or IoT devices.
- The TESTCOM program provides diagnostic routine to test your serial ports under MS/DOS operating system. It provides internal loopback test and external loop test. To test your serial port under MS/DOS, please type. Then screen will display as follows.
- E) Click on the 'Port Settings' tab. Click the 'Advanced' button. F) Click on 'COM Port Number.' g) Pull down the scrollbar and select 'COM1.' h) Click 'OK.' If there is no COM port or Other Device showing in Device Manager you need to enable the serial/COM port in the laptop BIOS, assuming the laptop has a COM port.

The mode command is used to view or modify a port or display setting.
Availability
Mode is an external command that is available for the following Microsoft operating systems as mode.com.
To install serial ports and COM ports using these system-supplied components, do the following: Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports. May 18, 2020.
Mode syntax
Windows Vista and later syntax
Configures system devices.
| Serial port: | MODE COMm[:] [BAUD=b] [PARITY=p] [DATA=d] [STOP=s] [RETRY=r] |
| Device Status: | MODE [device] [/STATUS] |
| Redirect printing: | MODE LPTn[:]=COMm[:] |
| Select code page: | MODE device CP SELECT=yyy |
| Code page status: | MODE device CP [/STATUS] |
| Display mode: | MODE [display-adapter][,n] MODE CON[:] [COLS=c] [LINES=n] |
| Typematic rate: | MODE CON[:] [RATE=r DELAY=d] |
Windows XP and earlier syntax
Configures system devices.
| Printer port: | MODE LPTn[:] [COLS=c] [LINES=l] [RETRY=r] |
| Serial port: | MODE COMm[:] [BAUD=b] [PARITY=p] [DATA=d] [STOP=s] [RETRY=r] |
| Device Status: | MODE [device] [/STATUS] |
| Redirect printing: | MODE LPTn[:]=COMm[:] |
| Prepare code page: | MODE device CP PREPARE=((yyy[...]) [drive:][path]file name) |
| Select code page: | MODE device CP SELECT=yyy |
| Refresh code page: | MODE device CP REFRESH |
| Code page status: | MODE device CP [/STATUS] |
| Display mode: | MODE [display-adapter][,n] MODE CON[:] [COLS=c] [LINES=n] |
| Typematic rate: | MODE CON[:] [RATE=r DELAY=d] |
Mode examples
Ms-dos Serial Port Configuration
Set communications port COM1 to 9600 Baud, with no parity, 8 data bits, 1 stop bit, and with XON/XOFF (these are the default settings). For those who are using Windows 95, Windows 98, Windows NT, or later we suggest modifying the ports through Device Manager.
Change the output video settings for the directory structure in DOS to 80 columns by 50 lines. If the lines or cols values are invalid, you will receive the error 'Invalid parameter - x,' where x is the invalid parameter.
Typing mode alone would display the current mode settings for all the ports, similar to the below output.
