the site says :Upload to Arduino device the ModBus RTU protocol..
when i put it in sketchbook and compile it says :As of Arduino 1.0, the 'BYTE' keyword is no longer supported.
Please use Serial.write() instead.
how to upload the protocol ?
...now i have uploaded the protocol by the arduino 0023 version ..but the server still wont recognise it..
How much information this contains? I mean, if you put yourself in other peoples position, how would this look like to you?
Try more text, less smileys.
