That chunk of code is entirely dependent on what 'uart_rx' receives. If it's not executing, that's because you're not driving it with '0x00' (8'h00) - a null character. Anything but a null character, as the first (an only) received character, will cause your state machine to stall in the 'H1S1' state.

Cheers,
