    hi there I have siemens gsm serial modem and I am having troubles also have the arduino uno to try to interface with it

    first problem is I just cant get the siemens to register on my new win 8 computer I did manage to get it to work on wifes 3 yo Toshiba win 7 computer but not even that works now
    so I am wondering if anyone has experience with these things and can help me a bit the siemens tc 35 is from ebay (china) and looks well made I have accessed it once and send a test message with it. the software offered with the device is in chinese and I have been unable to make any of it work
    I have had to install hyper term as it is no longer available with windows 7 and 8
    any ideas or suggestions would be appreciated

    Hi Ron and welcome to Electronics Point :)

    I can't help with the modem but I can suggest you use something better than Hyperterminal (i.e. anything other than Hyperterminal). In my experience, Hyperterminal causes its own problems, as well as being nasty to use. One thing that's worse than diagnosing difficult problems is diagnosing difficult problems with broken tools!

    An article on other replacements for Hyperterminal:

    These free programs sound good, though I haven't tried them:

    A shareware one:

    Windows is notorious for needing special drivers for devices. Linux on the other hand talks to generic chip sets mostly and therefore you might have a chance to make it work under Linux. Once you manage that, you might be able to find the required driver for Windows. I am guessing that the software included with the device includes the driver. You might try and install the software, restart the PC and see if the device appears.
