ehs6 on Linux. Running in multiplex mode from command line. | Telit Cinterion IoT Developer Community

Hi, guys. I have the following question.

I wanna to switch my modem to Remote SAT activation mode (AT^SSTA). And I'm able to do this connecting to my ehs6 modem from command line directly using picocom.

./picocom -b baudrate /dev/ttyACM0

After restarting the modem with AT^SMSO, I see the proactive commands from the modem. So, it is ok.

But now, I wanna to do this using multiplexor. So my steps are:

gsmMuxd -m ehs6 -b 921600 -p /dev/ttyACM0 -K /tmp/gsmMuxd.fifo -H -w -s /dev/mux /dev/ptmx /dev/ptmx

to start a ******, after that, I'm see /dev/mux0 and /dev/mux1 appears, I connect to modem through mux0 or mux1. Then I send the same command for proactive mode activation, I restart the modem, kill gprsMuxd and start it again, make another connect to the modem using m,ux0 or mux1, but I see nothing from modem. I do not see not SYSSTART, nor SYSLOADING as I see it connecting to the modem directly. But still can send an ATI commands and get the response.

Do anybody knows how to properly communicate to the modem using gsmMuxd from command line ?
