Basic question about Serial Monitor

I have what is probably a simple question:

I have this:

if (Serial.available()>=3) {
  // now at least 3 bytes are in the buffer.
  First = Serial.read() ; 
  Second = Serial.read() ; 
  Third = Serial.read() ; 
}

How can I use the Serial Monitor to send all three bits together so I can debug my sketch?

For example, I need to send 144,60,127 to the Arduino. Thanks!

You can't. The Serial Monitor application sends ASCII data ("144,60,127"), not binary data (144 and 60 and 127).

ok. Thanks. I'll just keep doing it sending real midi data. Cheers...

with midi, it's not so much the 3 bytes together, its still 3 bytes serial, just really fast. you can put multiple ascii characters into the serial monitor, and send them really quickly serially. so just put the ascii equivalent of your data.

problems arise however with midi, as key midi commands aren't represented in ascii afaik. i could be wrong.
