Does Vs+ and Vs- need to be connected on a TRS232E?

I have a TRS232 RS-232 Driver(max232 equivalent). On the data sheet, it shows a capacitor on Vs+ and Vs- (1uF)and they just have arrows saying they go somewhere. Can I omit these connections and capacitors and if I do what are the side effects or…

pinning of MAX232

I just want to ask if there is ever a connection between pin 2 and pin 3 of MAX232. I did a continuity test between those two pins. One of my MAX232 has shorted pin 2 and pin 3. My other IC does not have connection between those two. Now I am…
