We have a special display/LCD with a serial RS232 input. The data present in the RS232 port is shown in the display
We need to remotely control the LCD using the MTX-Tunnel GPRS-Serial tunnel
We can control the LCD in several ways:
We could develop a code for the server PC and use the TCP/IP port socket to connect to MTX-Tunnel.
This example shows how to do this in any third-party web page using a form. The form will have a user defined entry box, so the text data captured will be resent to the LCD.
