hi i am new ti autoIt and i tried the netcommocx example and it works great, but for my application i need the modem to stay connected and close the com port so other program can use it and communicates with remote modem. (i use it to connect to a plc) i am able to do it in hyperterminal with atdt+ phone number then close program and the modem stay connected, but with the example the modem disconnect as soon as the program closes. Is it something possible to do?
