two-way uart with ESP32

[bluemonkeysrock]

Hey y'all,

I am using ESP32 with a baseband modem that has 1 wire uart interface. I need to communicate with the device.
Can uart1 or uart2 be used as 1 wire full duplex uarts, maybe with a specific configuration (changing macros) ?

And one more question, does the MCU of the ESP32 (Xtensa LX6) have internal flow control, can't find it on the datasheet?

Thank you for your replies,

...how would an 1-wire full-duplex UART work?
