modem ttyUSB1 sometimes only responds after HKS toggle
When calling in after booting:

purism@pureos:~/addons/atinout$ echo 'AT+CGDCONT?' | sudo ./atinout - /dev/ttyUSB1 -

OKso only ttyUSB2 and ttyUSB3 respond to me. In this state, the Calls UI is not started when calling in and calling out times out. After modem HKS off/on, ttyUSB1 responds too:
purism@pureos:~/addons/atinout$ echo 'AT+CGDCONT?' | sudo ./atinout - /dev/ttyUSB1 -
+CGDCONT: 1,"IP","","0.0.0.0",0,0,0,0
OK
purism@pureos:~/addons/atinout$ echo 'AT+CGDCONT?' | sudo ./atinout - /dev/ttyUSB2 -
+CGDCONT: 1,"IP","","0.0.0.0",0,0,0,0
OK
purism@pureos:~/addons/atinout$ echo 'AT+CGDCONT?' | sudo ./atinout - /dev/ttyUSB3 -
+CGDCONT: 1,"IP","","0.0.0.0",0,0,0,0
OK
purism@pureos:~/addons/atinout$ and only then, calling works, in and out.
I think I see this since v5.9.11
