DTMF verification

Hi,

I wrote a short program, unfortunately I cannot test it, ( I have a dry line for my DSL) at home, it does compile fine, but would the following subroutine work as follows:
-Dials 514 670 1550
-pause 4 seconds (waits someone to pick up...)
-then for 20 seconds, sends the number 5 dial tone
-pause for to seconds before returning to program.


CODE/:
Dialnumber: 'subroutine

DTMFOUT PortA.2, [5,1,4,6,7,0,1,5,5,0]
pause 4000 'Pause 4 seconds
DTMFOUT PortA.2, 20000,0, [5]
pause 2000 'Pause 2 seconds
return

/END CODE

thanks
K
