hi,

I am looking for a USB RS232 virtual com port driver to enable a USB device (GPS)connected to a PC to be queried as a standard serial port

Which of the current FabulaTech products would be best to use for this application?

many thanks

Phillip

What kind of the device is this? As far as I understand you have a GPS which is USB device. But your OS system detects is as COM device (when you plug this GPS into USB port virtual com port is created, right?). And you need to access this very Device (virtual com port) from a remote location, right?

Please describe in detail what you are trying to do.

Thanks.

Hi Alex

thanks for the quick reply.

I am using Windows XP and Windows 7.

I have a CDC/ACM compliant GPS device which provides USB and com access.
I have code which queries the GPS via the RS232 serial port.
We are porting our app to new hardware and the new target PC's we are itnegrating with only have USB connections.

I need to be able to query the device over a USB connection as if it was connected to a serial port and I am looking for a generic CDC/ACM device driver that provides a serial port emulation on Windows operating systems by implementing a serial link emulation protocol on USB.

Hopefully my question is a little clearer now.

Any suggestions would be appreciated.

thanks

Phillip

Yes thanks, it's clearer now

But doesn't this very device when pugged into USB port create a virtual com port
like any other GPS device?

As far as I understand you need to work with your device locally. Or do you need to access this very device from the remote location? I understand that you need to query the device but could you please describe the whole project?

And could you please specify the model of the device? Does it create virtual com port when you plug it into USB port?

Meanwhile you can check our Network Serial Port Kit:
http://www.fabulatech.com/network-serial-port-kit.html

It shares com ports and connects them from any remote location.
