All screen output in FRED is sent to stderr.
The following is example screen output from a simple FRED run.

Outputing hitlists
Finished
The large block of .'s and x's are written to the screen as FRED docks molecules. Each . represents and sucessfully docked molecule, while each x represents a molecule that could not be docked and was sent to one of the undocked lists (see section 4.4.2). Any W characters that appear during docking indicate a warning was issued and sent to the warning log (see section 5.7.4). The remaining screen output is generally self explanatory.
