Hy!
Does INT_RDA also fire when I'm using the software UART of the compiler?

No.
The software UART, has no ability to receive a character, except when you have it sitting waiting for a character.
For _slow_ data rates, you can use an external interrupt pin for the RX line, and then call the software getc, inside the interrupt handler. A search here will find examples of this.

Best Wishes
