73
v1.0
Quiet mode
When on, there is no output from the modem on the serial side, i.e. you do not see OK, Connect etc.
Recommended setting for this option is OFF.
Send OK on carriage return
If enabled, will print OK every time CR is received on the serial side. Recommended setting for this option is ON.
Suppress line feeds
If enabled, line termination is using CR (13). If disabled, line termination is CR LF (13 10). Recommended setting
for this option is OFF.
Send OK on unknown command
Will send OK when an unknown/invalid AT command is received. Recommended setting for this option is ON.
Verbose mode

Table 19 - Modem emulator endpoint options
Circuit switched data (CSD)
The CSD (Circuit Switched Data) endpoint is designed for use when CSD connectivity is required between equipment connected
through NetComm Wireless routers. A typical application of CSD is a dial-up connection to an ISDN service. CSD calls use the
functionality of the GSM networking and switching subsystem to carry data via GSM or later cellular networks.
In many ways, this is similar to making a voice call. When a CSD connection is established, the communication end points are
connected via a virtual circuit, similar to connections on traditional phone network. Unlike other end points connected to a Modem
emulator end point, CSD relies mainly on the functionality of 3G/4G/LTE module. In CSD mode, the data stream of the router
transparently passes through the data and signals from the serial port to the module and vice-versa. The available data rates will
vary according to the network of the service provider. It is not necessary to have PDP profiles enabled for this functionality, however,
you may need a special SIM card with data functionality for CSD calls to be made. Check with your service provider.
