Hi,

I'm trying to send SMS using AT commands from a server connected to a RUT955 via 232.

Using Teraterm and sending any AT command to the router it replies "OK" without providing the expected answers, for example the AT+CPMS=? command.

On the manual I didn't find how to setup a 232 serial SMS gateway also it is not possible to trace the commands received from the 232 interface without being a privileged user.

Here is the configuration

Thank you
