Typical usage on the command prompt below. Please note that commands end in CR '\r' and responses end in LF '\n'. Neither end in both, so do not use Serial.println. The character in OOO is the letter O, not the digit 0.

Send     : ">SOOO\r"      //request state
Recieve  : "*S19OOO\n"    //returned state
Send     : ">B128\r"      //set brightness 128
Recieve  : "*B19128\n"    //confirming brightness set to 128
Send     : ">JOOO\r"      //get brightness
Recieve  : "*B19128\n"    //brightness value of 128 (assuming as set from above)
Send     : ">LOOO\r"      //turn light on (uses set brightness value)
Recieve  : "*L19OOO\n"    //confirms light turned on
Send     : ">DOOO\r"      //turn light off (brightness value does not change, just the state of the light)
Recieve  : "*D19OOO\n"    //confirms light turned off
