Hello Dragan,

Your modem does not support one of the modem commands that Diafaan SMS Server uses to retrieve the network status of the modem. The modem then returns a non-standard reply ('COMMAND NOT SUPPORT' instead of 'ERROR') and this invalid reply causes Diafaan SMS Server to reset the modem over and over again.

You can set the 'CompatibilityMode' property in the advanced settings of the GSM Modem Gateway to 'BasicPDUMode'. In this mode, Diafaan SMS Server only uses the most basic AT commands and the 'AT+CEREG?' command is not used. The only drawback is that in this mode Diafaan SMS Server does not ask for the modem and network status and you will not see this data in the status overview.

Regards, Henk
