Tx,Rx and ethernet"HELP PLS"

Hey,

pls i need your help guys i have two problems :

1- if any one know how to test ethernet ping,
2 - i have another board that has Rs232 communication so i need to send char caractere in the Rs232 terminal from my arduino mega to the other board ,

For your second problem have a look at the examples in Serial Input Basics - simple reliable ways to receive data. There is also a parse example to illustrate how to extract numbers from the received text.

The technique in the 3rd example will be the most reliable.

You can send data in a compatible format with code like this

Serial.print('<'); // start marker
Serial.print(value1);
Serial.print(','); // comma separator
Serial.print(value2);
Serial.println('>'); // end marker

A question would be punctuated with an question mark (interrogative).
