For sure there are.i am wondering if there's some UART transciever IC that would work over i2c (or SPI), so i can adress individual serial lines using i2c address a
Your application is quite unusual. (And I asume there are better solutions)
Usually one has one bus .. and many slaves connected.... and some addressing scheme.
Also do a serach for: Modbus, multi drop bus, CAN bus, RS485 ... and so on
Is it feasible to configure the UARTs in 9-bit mode so they become addressable?
The time you spend learning about FPGAs might be less than the time you spend debugging and weeping uncontrollably.
i have approximately 32 Linux servers with 115200 baud serial console and i would like to connect all of them to single ESP32.
I think you started with a simple and straightforward concept and are moving to increasing soft- and hardware complexity. If the simple concept does it (star wired RS-232 lines, a single concentrator device), why implementing the complex one?I think i will run daisy chained serial line through couple of uCs with at least 4 to10 times higher baudrate than the baudrate i need to handle at endpoints. I will inject some kind of custom packet headers to indicate which endpoint is origin/destination of the message. I guess that can be enough. Unless all terminals start flooding the terminal nonstop at the same time.

Maybe i can replace the daisy chain with i2c or something, but i am not sure about speed and possible length of wiring...
