hi,
I am debugging program code by using ISD51 debugger. In program I am calling ISDwait function. so the microcontroller 8051 has to initiate ISD51 debugger and waits until Uvision2 Debugger connects to ISD51. but it is not at all connecting to Uvision2 Debugger.

I am using alternate method without ISDwait to debugg program by using ISD51. thats working fine. but i would like to use ISDwait function in program. please let me know why it is not working.

this is my program

#include"reg51.h"
#include"lssd.h"
#include"port_init.h"
#include"t0_m1_delay.h"
#include <intrins.h>
#include <absacc.h>
#include "ISD51.h"
#include "keyboard.h"

void main(void)
{
unsigned char i;
port_init();
T2CON = 0x34;
RCAP2H = 0xFF; //baud rate = 9600 at oscillator
RCAP2L = 0xB8; //frequency = 11.0592MHZ
SCON = 0x50;
EA = 1;
ISDinit();
//ISDwait();//commenting this function to avoid ISD51 struck
keyboard();
_nop_();
while(1)
{
for(i = 0; i < 9; i++ )
{
lssd(LSSD1_ADD,i + 0x30);
}
}
}
