AN2606 RS232 (presumed dumb question)

If I had a suitable board, I'd just try the obvious, but I don't presently have one. I'm pretty darned sure this is a dumb question, but if I'm wondering, I guess others may do as well, so here goes.

In AN2606, it repeatedly says:

"RS232 serial interface (example, ST3232 RS232 transceiver) has to be directly linked to the USART"

I presume this is badly worded in that they do NOT mean connect the RS232 interface directly to the STM32, they mean that the TTL-compatible side of, e.g. an ST3232 transceiver, should be connected to the STM32.

I.e., any voltage compatible UART/USART serial lines like from another STM32 series device should fine.
