Both the question and the answer are mis-using the term RS232. RS232 is
only an electrical interface standard defining the voltages used for
a standard modem interface. What the Verilog code does, and I presume
what the OP asked for is called a UART. To have communication over
RS232 you typically need both a UART (or USART) and an electrical
interface (drivers and receivers or transceivers) to convert the
LVCMOS signals to RS232 levels.

I did a quick search on Opencores, and found dozens.

A basic UART with a fixed data rate is so easy that even I can make one.
Making one that gives you configureable this and that via registers is
harder, but straightforward.

Even me. One of the two times I've done HDL for money I had a UART in
there sending decoded information to a computer.

(I was reading call progress information off of someone's PBX -- that's
all I can remember, though).
