It would probably be helpful if you were to post the code you have and
explain what part isn't working. There's a function:
readFile :: FilePath - IO String
(FilePath is just a String)
which reads a file. This should be what you need to solve this
exercise...

Hi,
How can I take some input and convert this into a
PortID ?
I don't quite understand why the constructor
PortNumber doesn't have the signature
PortID = PortNumber Int | ...
Instead it is
PortID = PortNumber PortNumber
where PortNumber is not a member of the Read class.

Sorry,
I've just worked it out.
PortNumber is an instance of the class Enum
so we can use
toEnum :: Int - a
