correct use of MAX3232 for a single TTL to RS232 connection
Actually, the chip I use is a MAXIMs chip that has a different datasheet than the TI one. My chip is actually a one channel chip. I got confused because of initially using schematics from google. My bad, thank you for helping me find the answer with your comments.
