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
