problem with HyperTerminal and escape sequences pls help

Hello All

I am working with a energy metering project . I am using HyperTerminal privet edition v6.3 as my output terminal to show the voltages current and all the parameters . Keil c compiler and cygnal 8051f120 evaluation board are used for the development .


when I tried to update the whole content and update it with my new reading it takes a lot of time . I creates a burden for my program .so I tried ANSI Escape Sequence. I am facing some problem in this phase . some of these sequences are working fine while some are not. I tried with ansi and vt100 emulations

I got clear_screen(); and cursor_home(); functions working but I am unable to make out any cursor positioning functions so I am posting these functions with this letter expecting your kind help


void clear_screen (void)
{
putchar(0x1B);
putchar('[');
putchar('2');
putchar('J');

}//working



void cursor_home (void)
{
printf("%c[H",ESC,ESC);

}//working


void cursor_point (unsigned char row,unsigned char col)
{

putchar(ESC);
putchar('[');
putchar(row);
putchar(';');
putchar(col);
putchar('H');
}//->the output is ; H; H
