RS485 Hardware, Software, Direction control Example

Hi, working example is here: http://arduino-info.wikispaces.com/SoftwareSerialRS485Example

Any comments, critique, suggestions welcome...

Thank you for your great RS485 Example. I am trying to send a string of commands to a device using the same "brick" Can your sample handle input like "A4 D0 00 B4 E1"? Any pointers would be greatly appreciated...
