代码里面每一行send_buf的代码各是什么意思？还有yanshi(65535)为什么写需要这么多

程序如下：
void gsm()
{
led=0;
OLED_ShowCHinese(40,0,2,14,1);
OLED_ShowCHinese(40,2,4,12,1);
EA=0;
yanshi(65535);
send_buf("AT\r\n");
yanshi(65535);
yanshi(65535);
send_buf("AT+CMGF=1\r\n");
yanshi(65535);
yanshi(65535);
yanshi(65535);
send_buf("AT+CSCS=");
send('"');
send_buf("GSM");
send('"');
send_buf("\r\n");
yanshi(65535);
yanshi(65535);
yanshi(65535);
send_buf("AT+CSCA?\r\n");
yanshi(65535);
yanshi(65535);
yanshi(65535);
send_buf("AT+CMGS=");
send('"');
send_buf("13631893180");
send('"');
send_buf("\r\n");
yanshi(65535);
yanshi(65535);
yanshi(65535);
send_buf("finish work");
send_buf("\r\n");
yanshi(65535);
yanshi(65535);
yanshi(65535);
send(0x1A);
led=1;
bz4=0;
OLED_ShowCHinese(40,2,2,12,1);
OLED_ShowCHinese(72,2,2,24,1);
EA=1;
}
