Serial.write Returns ASCII Code?

Hi

I'm trying to understand why the Serial.write function is returning ASCII code values to my serial monitor when I try and write values. According to the documentation it should just send the value of the byte.

The bigger reason I'm asking is that we recently had a MEGA board go crazy and we think it somehow blew up another circuit board that it was connect to. It was one of those situations where everything worked fine and then it didn't. On the trial where it blew, the MEGA only sent ASCII code values instead of the numeric stuff it was sending early. I don't have access to the code that was running on the mega when it fried the other circuit, but we had been using it for a while now with no problems until this suddenly happened.

Thanks in advance!

Serial.write() sends only a single byte. If the value of the byte is something like 65 then you'll see something like "A" on your screen.

Serial.print(65) will send the two letters "6" and "5" to your screen. Serial.print(65, HEX) will send "4" and "1" to your screen.
