Calculon's Arduino Serial madness, part 2

Hello LMR,

Calculon has been tinkering with his Arduino for a few months now and he likes it. He is at the point where he is trying to get his 'duino to communicate with another device. His question is: HOW?!?!?

More specifically:

1. Does he use the Serial.print command? Serial.write?

2. How does he send more than one byte at a tyme?

3. Here's an example of the required byte sequence:

     in hex: 0x8D, 0x7F
     in decimal: 141, 127

Does he just send one byte, and then another?
