I have a suite of applications programs which are running on separete computers with WinXP and RedHat Linux. Computers are connected to each other via a local ethernet hub. Applications communicate with each other by TCP/IP and UDP without any problem. Now I need to put one of the computer on a mobile platform and it will communicate with the other computer over long distances via radio modem. (Wireless ethernet is not an option due to long distance).
How can I confgure WinXP and RedHat Linux to redirect its ethernet activity (TCP/IP and UDP) to serial port ?
