One thing that came to mind...is there a way to force a script to run from a PC? Seems like that may be easier. I can send a command to my PC from my remote to trigger that process.
Theres a few different ways this could be done, for example you could connect your computer to the PhotoBridge via the serial port and send commands that way.
I do know a fairly simple way to send commands, that might work ok for you.
If you use the command netcat its fairly simple to send commands to a unix system
One word of warning is (according to this web page) is that netcat is deemed a 'hackers tool' and so Norton Anti-Virus tries to remove it
Anyway, if you download Netcat for NT 1.11, you can use it as follows
First make a text file on your PC, lets call it vga.txt. In this file you have the following lines
ecp system videomode rgb 1080i
You can call netcat as follows:
type vga.txt | nc -t -w 10 X.X.X.X 23
where X.X.X.X is the IP address of your PhotoBridge.
The -t option tells it that this is a telnet session, the "-w 10" makes the netcat command quit after 10 seconds (to tidy up), and 23 is the port used by telnet.
So you could put this in a .BAT file or whatever on your PC.
As I said though, there are plenty of ways to do this, but this is pretty straightforward.
