Thanks Daniel,

There's another aspect to this case. It's not good practice to hammer on an SD card like this, even with wear leveling my three writes per second will reduce the useful life of the SD card to a short time, probably measured in weeks.

I'm happy to be a Beta tester for any multi data ...

Thanks Daniel

It might help if you had some hard numbers to qualify what I'm trying to do. The interface is RS-232, 115,200 baud.

Here's the GTT38A display with 6 graphs, 72 points per graph:

Thanks Daniel,

A command to enable BREAK recognition (default would be off, so operation as it is today).

If it has been enabled, a BREAK for a certain minimum time would cause a hard reset.

Hello,

I have six GTT2.5 Chart objects which I can update fine using gtt25_dataset_push_data(). In order to update them more quickly over an RS232 link, I'm writing a file to the SD card using gtt25_filesystem_file_write(), then executing the file with gtt_run_script(). The file simply contains 80 ...

Hello,

I have an application where the GTT38A is a few feet away from the hardware talking to it, via RS232. In the event of a communication loss, I need to be able to do a hard reset. I'd rather not have to do something to cycle ...
