Currently I am working on a Qualcomm cell module eval board. By default, the communication is on USB port right? But I want to talk to the module through serial port and configure the baud rate, data bit etc.


My question is how to use RDM (Runtime Device Mapper) to map services to serial port? I was told I can use the connect tool (ct.exe). But it doesn't have specific command option for that.


Is the procedure like first run the app on the target and then start ct remotely? Or can use other tools to map to serial port?


Another question is once the mapping is done, will the module keep the configuration or we need to do it every time we power the module?


Thanks a lot!
