Hello.

We use the RS232 connection of the RUT955 as a modem. The baud rate is set to 9600. After a restart, the RUT no longer understands the AT commands and responds with an incorrect baud rate. The AT commands are also sent during the reboot of the RUT. How can we reset the interface so that the commands can be understood again?

Hello Dirk!

Tell me, what kind of AT commands are you sending RUT955 through modem mode?

Hi Aliaksandr!

We send an atz. Sometimes a '+++' is sent.

Could it be that a '+++' triggers the problem, when it is first sent to the modem?

The only commands that can be used at the moment you can see here. The rest of the commands may have problems when used.
