Thankyou Ioannis and f Lez for your contributions, i got the point of no response from the virtual terminal, am wondering how can i make it respond, like when pic16f877 sends ''AT'' ,terminal is supposed to respond ''OK'',
Do i need to use two virtual terminals? pliz guide me

Thankyou Ioannis, i have decided to remove the option for the response from the phone since i think that can only be achieved practically not through simulation, BUT, i have encountered one problem!, When the push button(interrupt) is detected the microcontroller sends a message contineously, how can i stop this?, I want it to send a message only once on detection of an interrupt, my code is below
regards
code:

BEGIN:
if PORTD.2 = 0 then SEND_SMS
GOTO BEGIN

SEND_SMS:
sound PORTB.2,[100,10,50,10]
HIGH PORTB.6
HSEROUT ["at+cmgs=",34,"+256782277658",34,13]
PAUSE 1000
HSEROUT ["An interruption has occured",34,13]
LOW PORTB.6
pause 1000
HIGH PORTB.6
HSEROUT ["at+cmgs=",34,"+256772021358",34,13]
PAUSE 1000
HSEROUT ["An interruption has occured",34,13]
goto BEGIN

Isn't it obvious? What are your code doing?

1. Button pressed?

2. Yes, goto send SMS

3. Button pressed?

4. Yes, goto send SMS

5. .....

You are in an endless loop.

You may check if the button is released before sending another SMS.

Or have a timer to send every say 10minutes if the button is still pressed.

Or have a flag set in the sending SMS routine and cleared when the button is released

Or...
