I spend some time figuring out how to send AND receive serial commands to a Panasonic projector but got stuck on sending and receiving the STX and ETX commands .
In hope of saving others some time this is how I did it:
1)
Go to: File -> Presentation Properties -> Interactive and change the protocol to Binary
2)
Convert the ASCII command to Decimal. I use this page:

3)
STX in decimal is = 2
ETX in decimal is = 3
When sending a command from brightsign add a send command with Serial bytes (comma separated)
The power on command (PON) should look like this: 2,80,79,78,3
-----
When receiving signals from the projector it should look like this:
Question: Is projector on? send 2,81,80,87,3 ( [STX]QPW[ETX] ) when projector is on it returns: 001
In the serial input event you type in the following which is the decimal values for [STX]001[ETX]:
Specify serial input: 002,048,048,049,003 (this only works if the protocol is set to binary as described in the top)
