    Default One for the Linux/virtual box/windows guru’s

    Hello guru’s,

    I have a Linus base system with a windows7 in a virtual box.

    I am trying to get the windows system to see the serial port on the computer (/dev/ttyS0).

    I have done a chmod to make the /dev/ttyS0 accessible to all users (ie me).

    In virtual box I have enabled COM1 and piped it to /dev/ttyS0 yet applications do not see the serial port.

    I am at a loss what to do next.

    Any pointers?

    Thanks for looking in.

    Sorry I cannot help. Not may area of expertise, I'm afraid. Sounds like a good question to be posed on the relevant Linux forum. i.e. the forum relating to the version of Linux that you run.
    I'm out of my mind, but feel free to leave a message...

    The serial port is an actual true serial port with linux as the base system (/dev/ttyS0).

    Win7 is the virtual system with a virtual COM1 that I need to access the actual real COM1 (/dev/ttyS0) under linux.

    the virtual box that windows runs in does not have any actual serial ports. everything is virtual so ser2pl should have no effect as I am trying to link a virtual COM port to an actual COM port (not a com port through USB).

    Quick google talks about serial to USB. I am wanting to go serials to serial. USB is not require to access.

    I can't find it again now but I think I remember when trying similar a few years ago something about having to create or enable the COM port manually from within the guest OS?
    That was with XP as the guest I think & from memory I think I gave up trying after a while.
    Never really had much luck with VB over the years, never seemed to be able to get it working as it was supposed to.

    This might have been what I was thinking of -

    What I was wanting to do was run a rtlsdr under Linux and use my Winradio under windows on the same machine at the same time.

    The solution may have to be solely windows. But that has its own issues.

    Winradio work using WINE?...though I've found WINE & anything USB never seem to play nice together.
    Or perhaps as another option.

    It’s not USB. My winradio has a rs232 port.

    Aah ok, never used Winradio or similar, when I looked it up I saw something about USB interface mentioned somewhere.
    Above my level of expertise I'm afraid...

    thats ok. just my luck there will be some strange solution like a Serial <> USB in Virtual box into the Linux host system where /dev/ACM0<>/dev/ttyS0!!!!!!!

    I might give wine a try at some stage...hopefully when all finished and working will give me a listening station from 100KHz to 4 GHz all modes and digital?????

    What about ditching WINE and trying Virtualbox instead? Presumung you still have a valid Windoze licence, of course.

    Sorry, missed the bit about VB. If you can's get it working in VB, I'd give WINE a miss, the Linux forums I inhabit see more problems with WINE than VB.

    Hi Porkop, In Virtual Box did you install the guest additions ?
