ISD51 connect error

I have isd51.dll ver 2.34.

I would like to use an ISD with TI TUSB3210 processor (like standard 8052 derivate).
And I've got an Error message from
ISD51 Monitor Error:
'There was no reply from the target system!'

I correctly set baudrate to 9600, tested both in simulator and hyperterminal as well described in ISD51.htm file. The function with 'A'character and output character work perfectlly. So I go back to simulator and try send HEX 0xA5 by sin=0xA5 command in simulator - it display 0xF7 followed by 6 hex values. => It seems that all work OK.

But when I try it in Hyperterminal it does'not work. So I think that when Debugger send initial command - no response from 8052 by UART.

Where should be an error ?

    this I forgot, so I disable T2 and use standard T1 as baud rate generator.

    Can I use these values ?

    TMOD &= 0x0f;
    TMOD |= 0x20;
    SCON = 0x50; /* enable serial uart & receiver */
    PCON = 0x80;
    TH1 = RS232_BAUDRATE;

    TR1 = 1; // enable Timer 1


    2) I am using TUSB3210 chip for USB HID transfer protocol. I would like if it possible to discuss about it. Something I understood but something not. If anyone is interested in TUSB chips - it should be good to discus about it.
