    I need a terminal program that will allow me to see the data stream coming in from a USB device plugged into a USB port on my window 7 PC. Is there such a thing?

    Hi, Please can you guide me how can i connect wight balance machine rs232 with PC and get auto weight on my computer screen

    • HI,

      First check whether your PC has a serial port or not.

      If not then you have to use an USB to RS232 converter cable.

      Install the driver from the cd of USB-2-RS232 converter into your PC.
      It’s provide a virtual serial port to use.
      Now connect RS232 part to your device and USB part to your PC.

      Power up the weight machine and open a hyper-terminal or any other serial port utility or software provided by the machine vendor and start the communication.

      Configure serial port properties according the user manual of your weight machine. To know about serial port settings read the full post.

      Hope it’ll help you.

      Have a nice day!!!

    Hi. Thank you for the article.
    I need to send a File over serial port, but I think it’s impossible with putty becasuse this program don’t have some menu for this action, it’s true?


    • Hi Manuel,
      Thanks for your comment.
      Putty does not have that option.
      If you are using windows then use hyper terminal(download it form the link given in the article) and in linux you can use “minicom”.
      Minicom also ha option for file transfer but I did not use it personally so i might not be able to tell you about it in detail.

    I’ve 2 systems, system A (host – windows OS) and system B (target – windows OS). So I’ll connect a serial cable from system A to system B. From system A, I would like to go to system B – C drive, how can it be done through COM port?

  17. You can use putty, teraterm and other similar terminals for serial port communication.

    Hyper terminal? Ir reminds me of dark ages of PC communications 🙂
    Why not using some more modern terminal
    for example
    with macro messages setup (even adjustable one) and scripting and all it is much much more powerful tool to develop serial port communication or simply test device.

    Of course there are many other programs but I prefer docklight since it is made so many years ago and it is still maintained and updates so I like to think it is mature an bug free 🙂

  24. I use Hyperterm to contro/read GSM modem. Is there a way [software] that can do the folowing:1. Access data from GSM modem 2. Process that data. 3. Store in Excel sheet? OS: Windows Vista

    Sir I have an issue with hyperterminal… when I open up the connection type, all its showing me is TCP/IP and dont have anything for COM PORT or any other option.

    • Anonymous says:

      Are you sure that you have com port? Check it in devices manager. If you do not have com port, you cannot select it.
      I know that at least docklight is providing list of only existing ports to connect.
