Using firmware 3.009 on an X750, I’m having trouble getting cat /dev/ttyUSB2
to read AT command responses issued on the same port. I am able to open up cat on the other ttyUSB* ports, but when I try on ttyUSB2, nothing happens, I’m just served another shell prompt (instead of blank line break and stream of content being written).
I notice AT command and response works fine on ttyUSB2 right after a fresh firmware install, but not once I’ve configured the device as needed. I’ve attempted to isolate a package or config setting that’s causing the issue but so far have been unsuccessful. Perhaps someone here has already figured this one out or has a tip on what to look for in my logs to determine where there might be a conflict (already tried searching for messages about ttyUSB2 being locked by another process, etc.).
I tried writing AT commands and listening for responses on all /dev/ttyUSB* but was unsuccessful. The LTE module is an EP06-A and ttyUSB2 AT command/response with cat works using the same firmware, configuration and installed packages on a MiFi.
Is there a different port to issue/listen for AT commands on the X750? Thanks in advance.
