These things are going to be a nightmare for exams; what's to stop two
students from pointing their calculators at each other and exchanging
answers!!!
Given the timely introduction of these boxes - just before the April
exams, please spread the word to those who oversee exams to be on the
lookout; not many people will know that these calculators can communicate
with each other at 2400 baud clear across a room over the infrared link!
Oh HP, what hath thou done!

I thought of this also and tested it with my HP-48 and my friends HP-48. They would not work past about three inchs. I wonder if HP did this on purpose? I will really get excited about HP IR when it can generate TV remote signals... Warren Furlow

Ah, this is true, but what of those devices you can buy for your TV remote control that boosts any IR signal something like 1*10^60 times so that you can freeze frame Dave Letterman from your garage? Granted this would only allow for one-way communication at any give time, someone _could_ give it a try. I think Rabbit (same company that makes the VCR transmission gadget) makes something like this. just another crafty undergrad... ;-) Louis Koziarz University of Illinois at Urbana/Champaign koziarz@uiuc.edu "The trees are in the street and the creek's on fire...must be home!
