UART Hardware Flow Control is broken for #PinePhone 4G LTE Modem 🤔

So what's your take on this? It seems UART isn't supposed to be the interface used and the designers intend you to use USB. Why are you trying to use the UART with hardware flow control when it's not wired that way? Of course it won't work unless the bandwidth is trivially low and the system was designed to not block, etc. Does it also not work with hardware flow controll turned off? I'm not an expert, but do own a pinephone.
@AmpBenzScientist @poleguy Mine has the Ubports Logo, so PinePhone v1.2 I think...
