Can you use Vixen to control the Prop-2 during a show?

I've been playing around with Vixen now for about a day, and I can see how it's easy to set up triggers and events in the software, and then have it generate the code to upload to the Prop-2, which then takes over as a stand-alone, which is great. It simplifies setup tremendously.

What I'd like to do is use Vixen to communicate directly with the Prop-2 during the show and run the show from Vixen.

Is that possible?

Yes.  A long time ago we created a demo driver that would run eight servos (P0..P7) and eight digital outputs (OUT8..OUT15) on a Prop-2.  In Vixen you would use this driver:

EFX-TEK Prop-2 8+8

Here's the source code for the Prop-2 that holds pertinent details:

' -----[ Program Description ]---------------------------------------------
'
' This program serves as a slave interface to Vixen (www.vixenlights.com),
' when using the Prop-2_8s8d.DLL driver.
'
' Connect to PC using the Prop-2 programming port.
'
' Note: Set the Vixen Prop-2 driver baud rate to 9600 (this is the fastest
' practical baud for using the WAIT modifier of SERIN which is required
' to maintain sync with Vixen packets).
'
' Note: The best Vixen Event Period (Tools\Preferences\EventPeriod) is
' 40 ms; periods shorter will cause some packets to be missed by the Prop-2
' while periods longer may result in "rough" servo movement.
'
' Remove the SETUP jumpers from P12..P15.

Ok, I had seen that earlier, and it's closer to what I'm after.

What I want is 2 way communication, where the Prop-2 will tell Vixen when a sensor has been triggered, and then Vixen can kick off the appropriate event. Sending on and off commands for the various outputs.

Would that be possible with the current set of Vixen plugins?

[edit]
It looks like what is missing is the ability for an Input Addin to Vixen. Without that you can't capture anything from the serial port, you can only send.
Back to writing my own program. :)
