STC15W408AS UART1 not working

[Adil-Sil]

Hello,
I am using STC15W408AS, code downloading from STC-ISP working fine everytime, but in my project's code UART1 never transmit or receive single byte, I tried several examples/chips but same failure occurs.
Is there is any solution. Code is [at:]

I think this is problem in chips.

The reason is the same as here: #105 (comment).
Try to replace these lines

TL1 = (65536 - (FOSC/4/BAUD));
TH1 = (65536 - (FOSC/4/BAUD))>>8;
TR1 = 1;

to

T2L = (65536 - (FOSC/4/BAUD));
T2H = (65536 - (FOSC/4/BAUD))>>8;
AUXR |= 0x15; // T2R, T2x12 and S1ST2
