I have a suite of applications written in BCB6, Delphi7 and Kylix3.
They 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 ?

There is no configuration for that.  You will have to either:

1) re-write your code to access the serial port directly

2) make a separate proxy program that the main application can connect to
via TCP/UDP and have the proxy forward everything back and forth to/from the
serial port.

3) write a low-level NDIS driver that hooks the socket stack directly and
then handles forwarding data to/from the serial port.  I don't know if this
will work for Linux, though.
