Hi. I'm trying to use the SCPI parser on e ethernet connection instead of the serial interface, but I'm having some issues getting this to work. is there a simple way for this to work and change from serial to ethernet ??

Current code looks like this: /* Web Server

A simple web server that shows the value of the analog input pins. using an Arduino Wiznet Ethernet shield.

Circuit:

Ethernet shield attached to pins 10, 11, 12, 13
Analog inputs attached to pins A0 through A5 (optional)

// Initialize the Ethernet server library // with the IP address and port you want to use // (port 80 is default for HTTP): EthernetServer server(80);
