Ah, good one ! I was just thinking inverter when I saw your post, but I
am not an electronics engineer by any stretch of the imagination . . .
wasn't sure it would work.
@Winston.
OK, my bad. I was actually thinking this could be the case, but was unsure.
Harvey's suggestions seems

I'll admit to being one
I have a similar problem with a display

Once configured, the TX line will overpower the weak pull up resistor.
