I am looking to use the ethernet shield to send commands from a VB6.0 program using winsock to the Arduino. Basically send a command like "Left1000" and the arduino will output 1000 pulses on a pin (for a stepper motor).
To do this I am setting the arduino as a server mode which waits for client input. I need to figure out how to parse the data the arduino receives. (I am fine with modifying the commands sent if something simpler, albeit more cryptic, would cut down on the parsing).
Any thoughts? Examples of sending commands to the Arduino through ethernet?
