Hi, take a look at my librs232 here http://github.com/ynezz/librs232.
Using it is easy:

#define BUF_SIZE 20
usigned char buf[BUF_SIZE] = {0};

struct rs232_port_t *p = rs232_init();
rs232_set_device(p, "/dev/ttyUSB0");
rs232_open(p);
rs232_set_baud(p, RS232_BAUD_57600);
rs232_read(p, buf, BUF_SIZE, &len_read);
if (len_read > 0)
        fprintf(stdout, "read: '%s' len: %d\n", (char *) buf, len_read);
else
        fprintf(stdout, "read nothing...\n");
rs232_close(p);
