..Heck- maybe I should go about this a different way...I've never delved into the config.ini file, but I have to bet that there's a way to use Mark's EXEC functionality to run fidsift all on the empeg.
You already are
using Mark's EXEC functionality here, to run
Mark's fidsift.sh on the empeg.
I strongly recommend that you (a) get yourself a real O/S to run FTP from

, and, even better, (b) connect via the serial port and run the fidsift.sh command from there.
FTP is a dicey enough environment for this stuff, let alone trying to use it from an "O/S" that doesn't really grok the internet.
