I don't have your office email address. I have uploaded a sample show file you can download at http://sparkyb.net/temp/serialmarker.pt3 . It is a very simple example of the problem I have. This show contains a single timeline with 2 position markers. After each it sends a message to the display on the SC Master 16 and then stops. Directions for reproducing the problem are as follows:
1. Download this show onto a CF card.
2. Start up a SC Master 16 with this card in it.
3. Connect any device capable of sending serial commands (I've testing with a PC and second SC Master 16) to either RS232 port.
4. Send the command "aSI001#". The display should (correctly) say "No Marker"
5. Send the command "aSI001M001#" or "aSI001M002#". I'd expect the display to say "Marker 1" or "Marker 2" respectively, but it only displays "No Marker" as if it is run from the beginning, and not started at the specified marker.
Do I misunderstand how this feature is supposed to work? It appears to totally ignore the rest of the command after the show number. In fact, you can put almost whatever you want after there and it will still start the show as if you hadn't put anything. Another command I tried was the "aJMyyy#" command. This command did not do what I expected either, but it did do something, I'm just not sure what. The display changed to "Begin of Show" or sometimes "End of Show" but didn't seem to have anything to do with the markers in my show.
Also, I know that the command "aSAxxx#" works to add a show, even though it is not documented in the SC Master 16 manual. Are there any other undocumented RS232 commands I should know about?
