I m using max232 with db9 and want to know that when we transmit bits serially from pc through db9 to max232's 13 pin, here we receive serial data in max.. But when we take output on 12th pin of max, is that pin always on high logic (3.68v aprox)..i think it should not be at high logic. Isn't it ? Please tell me.. Because i m having high logic on that pin(12th) before n after sending data bits.
