The microcontroller sends data, and the serial port assistant receives 0\ [Copy link]

When the 51 MCU sends a string, all the characters displayed on the serial port debugger are "0\". During debugging, I display each character on LCD1602 first, and then send it to SBUF, but the computer cannot receive these characters. What is the reason? The following figure shows the received content:

void Init_timer(void) //Timer 1=0010 Timer 0=0001 { TMOD = 0x21; //???ù?????? SCON = 0x40; //Set to 0x80 and the result is the same TH1 = 0xFD; //Baud rate 9600 TL1 = TH1; PCON = 0x00; //Do not multiply// EA = 1; //Do not receive data// ES = 1; //Do not receive data} Code for sending characters: void StartRs232(void) { TR1=1; //???????? for (i=0; i<16; i++)//???????????????????????? { LcdWriteCom(0x8f); //??????????????????????????? LcdWriteData(CsSz[i]); SBUF = CsSz[i]; while(!TI); //?????????????? TI=0; //????????????λ } }

I added the sending code according to the information, and sent data to the microcontroller through the serial port assistant, and the returned characters can be received normally. See the figure below: Note: This may only be the sent data, not the received returned data.
