Further to my question about the caps and theie orientation, I think that if a polarised capacitor is used for C1 its +ve must go to ground.
A negative voltage is taken from the Tx terminal (Rx) and stored in C1. The -ve is used for sending RS232 high from Rx rerminal (Tx).
This is a way of level matching the return -ve voltage to the received one irrespective of what shifting and combination is done by the rest of the adaptor before it goes to remote.
I think I should invert C1 before my RS3232 arrives, do you agree?

Then I connected a RS232 to usb converter from the programming Plug to the PC, didn't work out.
Tried it with a CH340, didn't work as well.
With a CP210x it neither worked.
Did I miss something out?

All Arduino boards have at least one serial port (also known as a UART or USART), ... Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V ...

Would these boards im gunna attach might work instead of this cable by any chance, because i already i have them
