Bashscripts.org

I'm writing a simple script to take the input received from a embedded bar code scanner to keep appending to a script.
According to the manufacture of the Linux based scanner "the scanner data is redirected to appear as user input,and to just use the bash script 'read' command."
So my simple test script is:

Nothing is being sent to the foo.txt file.

Any ideas?
I have googled to no avail thinking maybe the read command requires something since enter is never pushed.
Any ideas on what I should try?

isn't there an error message?

/jffs2/data/foo.txt surely doesn't exist, and you cannot create it, as it is at the root (/) of the filesystem.

Turns out the vendor of the scanner failed to tell me I had to change a setting to get the scanner to work this way in scripts.
meh.....
Thanks
