I have been using .1uf caps in years with MAX232ACPE didn't
have any problem with it only very old max requires electrolytic
no body uses electrolytic takes too much space and more expensive.
By the way you can also use tantalum caps it is even more expensive
then standard electrolytics sure why not.
