Transferring data from serial RS232 channel
to an Ethernet based TCP/IP

Hardware configuration. One eZ80 Webserver board is programmed with serial sender software. The other one is programmed with the serial to TCP gateway software. The boards are connected with a serial cable using the UART1 ports. The second board is connected to Ethernet. As soon as the board is configured to work with a certain Host server and activated it listens for input information on UART1 and accepts the incoming serial frames of data. It copies the information to the TCP/IP packets and sends it out to the Host.
