I would like to share data between a laptop (without a serial port) and a desktop (with a serial port).  Both have usb ports, and a cable is available from USBGEAR  to connect the computers.  This connection also comes with file transfer software.  From what I've read if I had 2 serial ports I could communicate by doing a CreateFile with a file name of COM1, then normal reads & writes.  Does anyone know if I can do this usb to usb, if so how.  If I use the CreateFile etc method what file name do I use.  Any help would be appreciated.

Most of the USB cables you mention just emulate a COM port - might not need the software at all. I've never used one, but have done a lot research on USB ports and the hardware / software involved. OMG, is it convoluted. Never used COM ports through windows either. (Don't we just OUT data to the port/registers. :lol:)

I'd go the wireless network route - especially if your laptop has WiFi.

I think BitRAKE is on the right track. I remember doing such a thing through "Direct Cable Connection" or something like that... years ago.
