I bought a max233 to help improve my studies but I ran into a bit of
problem. I was building a schematic from the nuts and volts article
#89 (which I had to convert to 233 because they use 232) and just for
the heck of it I wanted to see if my serial port complete book, by
jan axelson(which is way over my head) and to my astonishment the
schematics looked totally different. I bought the max233 because I
didn't have to have external capacitors(or so I hard). Any tips or
places to go? maybe these 2 schematics do the same thing but are
just hooked up differently? I don't really care about bruning about
an $8 chip but it would really put a dent in my wallet if my comps
port got blown out (is that even possible?) Thanks for your help in
advance
