I need a program for Windows 2000 and XP that makes those operations:
-It must monitor the modem (I could select the modem that I would like to monitor)
-When the phone line ring the program should start to enter a script
of AT commands that I wrote.
-Every line of script can be wait an event before execute the next
line. The events are: wait for a string, wait some seconds, execute
the next line immediately.

an exaple of script:
-----------
at! (wait any string)
atdt123456789 (wait 3 seconds)
+++ (wait 2 seconds)
ath
-----------
(the script sintax can be different if you prefer)

The program should can be executed also like a service in Windows.
Thanks
