I think in order to receive SMS messages, the serial port must be open. It would be nice if the application had a service to periodically check the availability of the serial port.

I got the same error several times, but I can't pinpoint the specific timeout issue. I tried sending AT commands using SerialPort.Write() (without ATLib) and it works fine.

You should not need to close the modem connection between commands.
What modem do you use? Does it happen after a certain command?

Modem : Fona
