Serial Port Isolation

One of the potential challenges I have is that I have a lot of things wired together via RS-232 (or other) serial connections and this creates quite a web of potential ground loops and also makes the entire electrical system vulnerable to problems. What I would like to do is start opto-isolating some of these connections, especially connections that run up the mast (anemometer, etc), so I am curious - does anyone here have any recommendations for isolating serial lines ? Component level is fine so long as they are DIP chips and not surface mount, my eyes aren't what they used to be.

Thank you!

What are you pretending not to know ?

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Yes, of course I am looking for solutions myself too, but I like to ask sailors because, who knows, maybe some smart sailor out there has been there done that and they have some magic box that costs 5$us that does it. Sailors are a creative bunch and I have found them to be very innovative, sometimes with surprising answers that are out of the norm.
