how to erase a line of LCD ? [resolved]

Hi there,

I'm using the flex_lcd420 driver and I'd like to erase one selected line from the four lines in my 4x20 HD44780 LCD , I'm wondering about what I should put in lcd_putc().

I have the following function in the lcd driver :

Code:

void lcd_putc(char c)
{
switch(c)
{
case '\f':
lcd_send_byte(0,1);
lcd_line = 1;
delay_ms(2);
break;

case '\n':
lcd_gotoxy(1, ++lcd_line);
break;

case '\b':
lcd_send_byte(0,0x10);
break;

case '\&':
lcd_send_byte(0,0x0F);
break;

default:
lcd_send_byte(1,c);
break;
}
}

any suggestion ?

thanks in adance.
