I wrote a simple tcp server core program. However, it is very limited. It seems it can only handle a single device connected to it like a phone, but not two phones. Also I was only able to display the core values but did not know how to set them using the same browser interface. Here’s a screen shot and my code. So I need help on how to get thisto work or do I need to do this totally different.
The core is using semi-automatic mode.
Thanks again folks
