Problem with zero 0 in string

In am trying to SEND_STRING to device from buffer, in facet when I receive sometfing from one device, i remove few bytes, and want to send it to another device.

Problem is that

SEND_STRING 0:1:0,somevariable

is sending UP TO ZERO !!!!!

Is there solution to solve this ?

I don't know if this is your problebem but
when doing IP that ports 1 & 2 are reserved.

This is a fairly well known problem, but it only affects your debug window, and terminal screen (send_string 0). The null character goes out the port just fine, you just won't see it on screen. Apparently the display routines use a library that terminates strings on a null, so when it hits the zero, it stops displaying it. But it's only a display error, the code still goes out the port.

You can also just convert your string before sending to 0.

           STACK_VAR CHAR cProj_DeBug_Str[1024] ;

           nLenStr = length_string(DATA.TEXT) ;
	  for(n = 1 ; n <= nLenStr ; n++)
	       {
	       if(n == 1)
		    {
		    cProj_DeBug_Str = "itoa(DATA.TEXT[n])" ;
		    }
	       else
		    {
		    cProj_DeBug_Str = "cProj_DeBug_Str,',',itoa(DATA.TEXT[n])" ;
		    }
	       }
	  fnProj_DeBug("'RX STR (DECIMAL): ',cProj_DeBug_Str,' :DEBUG line-<',ITOA(__LINE__),'>'") ;

This will print out the ASCII representation of the incoming decimal values. Do the same for outgoing if you choose.
