sending a string via serial port ( SIM300 with 8051 )

[Kesa2211]

hey,
i am interfacing SIM300 with 8051 and i want to send sms to a group of mobile nos.
In order to do serial communication need to send string via the serial port. how do i go about it?
for sending a single character i can assign the character to the SBUF register but how do i do this in case of a string? How to write a function which will send a string through the serial port?

if you are using C you can simply use
serial_init();
char str[30]="AT+CMGF=1";
printf("%s",str);


void serial_init()
{
intialize UART for 9600
}
