`QuickRS232` is a versatile `RS232` `FPGA` `Verilog` module with following features:

* ***Internal data buffering*** with `FIFO` builtin in `RS232` with parametric `FIFO` depth;

* ***Full-duplex mode*** (as `RS232` standard supports) with parallel Receive (`Rx`) and Transmit (`Tx`);

* Supports ***either `No Flow Control` mode or Hardware Flow Control*** mode (`RTS + CTS`);

`RS232` timing diagrams (`115200 bod/s`, `even parity`, `no flow control`):
