Thanks for the reply, disabling the mux and cold booting the whole system, I can enter serial0 and it works as expected, can send commands and get gps data from it, no garbage characters.

Using sudo reboot, then resetting the SARA-R5 by connecting to ground lets me run CMUX again and it works as expected.

I am still having the issue where after entering cgps or gpsmon, the serial connection through minicom becomes unresponsive. If I enter ttyGSM3, no data comes out, and if I enter ttyGSM1 or ttyGSM2 I am no longer able to type anything, and even exiting minicom with ctrl+A, Q becomes laggy.

Blip, blop, bloop…
