delay_us with variable delay+mikroc

I have developed this simple program using mikroC. Can i change the delays given in this program using serial communication of PIC18F252 with PC? (by denoting time with some variables)
Please give essential conditions required for interfacing.

#define switch PORTB.F0
#define Pressed 0
void main()
{
TRISC=0;
TRISB=1;
PORTC=0;
PORTB=0;
for(;;)
{
if (switch == Pressed)
{
PORTC=0X02;
Delay_us(1);
PORTC=0X00;
Delay_us(240);
PORTC=0X04;
Delay_us(1);
PORTC=0X00;
Delay_ms(2000);
}
}
}

If there's any other way, than also please let me know?
Thank You.
 

pic18f252 circuit

declare a variable and use that with Delay like Delay_ms(x);
read a value from UART and assign that to x.. x=getc()... and just use it...

if u need more get the question more specific
 
#define switch port b.f0

Thanx a lot for your reply sir.
In my project I need to change these delays frequently. For that, I have to burn the hex file in the PIC again & again. To solve this problem I want to send these delays through serial communication.
Sir, please give me an example to send these values, like if you can write this program again with the required changes.
Can you please provide me the circuit for serial communication?
