Serial Commication RX/TX data bits 7 parity Even stop bit one

Yes, some of us still have to work with older serial schemes. I like the idea of just setting the control and status register to get me the 7Bit 1Start 1Stop EvenParity setting, but how do I tell it which serial port to apply the settings? On my application I will be using three serial ports, but only one needs to be configured as above.

For that matter, how do I set a register? It looks like all I have to do is:

UCSR0C = 0x24;

Is that correct?
