Have anybody ever used Moxa RS232 Servers to control shutter programming using Isadora?  I use them when I'm using Watchout, because there is a more robust set of settings you can change via RS-232 with Pansonic projectors than with straight TCP/IP control... specifically you can change the Shutter Open / Shutter Closed speed on the fly.

In Watchout you send a text string containing the RS232 control commands to the Moxa box via a TCP send message, and then the MOXA box converts the TCP string to a serial command for the projector.  I've tried using the TCP Stream Control actor to open a connection to the MOXA box, and then sending the string command through that stream using the TCP Send Data actor, but to no avail.

Has anybody every had any success with this?
