[En-Nut-Discussion] printf/putf %S for string in flash?

[Ralph Mason]

And I have added support for %P (program chars).  Limitation's : None :-)

        case 'P':  //Program Chars
        
             cp = va_arg(ap, char *);
             xdigs = buf;
             n=0;

             while(1){
				u_char ch = PRG_RDB(cp++);
				if ( !ch ) break;
				*xdigs++ = ch;
				n++;
				
				if ( n == BUF ){
 					_putb(fd, buf, n);
 					n=0;
 					xdigs = buf;
 				}
             }
             _putb(fd, buf, n);
             size=0;
             sign=0;
             break;

I doubt either will we added.
