Bash: Check if enter was pressed

How can I check in Bash if the Enter key has been pressed? I'm using the read command:

read -p "Please press ENTER" var

You can also check the length of the $var variable after it was set by the read call. If it's 0, the user just hit enter without typing anything else:

read -p "Please press ENTER" var
if [ ${#var} -eq 0 ]; then
  echo "Enter was hit"
fi

Firstly, check whether the exit status is normal ($? should be 0).

Secondly, check that $var equals "".
