    Hello.

    Can I use any of your products to accomplish this?:

    We have a number of wireless RS232 modems each connected to one WinXP(Embedded) computer. Currently, the application sends directly on the serial port to send data. What anyone sends, anyone receives. 3..10 users, small amounts of data, and there is a fair amount of garbled data.

    Because of this I would like to implement TCP/IP to control the data.

    I would like to try to have a virtual network adapter installed (WinXP Professional / Embedded). The virtual network adapter should connect to the wireless RS232 modems through a serial port on the computer, and the virtual adapter should forward all data inside Ethernet header to and from this serial port.
    I would like to install Microsoft TCP/IP service on top of this virtual adapter, and then use sockets in our application to use TCP/IP.

    Anyone have a suggestion on how to accomplish this?

    Thanks for your time and help.

    I see two possibilities:

    1) Create a virtual network interface on top of RS232
    2) Use VirtNet+WinpkFilter+special application working with WinpkFilter passing data between RS232 and VirtNet adapter.

    First approach requires driver coding but more solid in design, second one can be implemented completely in user mode.
