Yes, I know - it covers that in the manual. I've already done this
actually. Instead of dedicating 2 modules simply to do this job, I was
thinking you could probably build something with $1 worth of IC's & free up
those modules for other things. Also, it's a pain to have to patch that up
every time you want to switch back & forth.
I was interested in hearing from people who have done this or thought about
out it.
