I popped in a MC 1488 and MC1489 from the bits bags and I'm off to try it. Thanks to all for the help

If you have a circuit for the optical RS232, I'd appreciate it, as it will save me thinking. I'll build a few.
It should surely be possible to opto-isolate rs232 so that blow-ups on one end don't take out the other end as well. I wouldn't necessary go for optic fibre. Just some silly little box to go pop and save the computer.
This would not work in a coal mine. Been-there-done-that.
Fortunately, the customer is not in a coal mine. If it survives typical hazards (cursing, urine, beer, dust, lighting cigarette butts, noise, fire extinguishers etc.) that will do fine.
If you do want to make some, Agalient (sp?) makes the plastic fiber and some
plastic fiber transceivers. Get a couple of those and hook up to a MAX232 on each end. I think B&B Micro, and/or Black-Box, sells such a thing off-the-shelf.
Agilent, I think (HP in disguise - that lot?)
I'll have a look. Anything beats thinking.
