Just to make sure that I correctly understand, what do You mean: Pin 3 is Txa for 8i20, so I have connected to non-inverted input of SN75179 chip. I really tried to extra careful to make them right - Tx from my converter to Rx of 8i20 and vice versa. I measured - pin 3 is 3,93 V above GND, pin 6 is 0,96 V above GND.
