PHS8-P not respond | Telit Cinterion IoT Developer Community

Hi!

I tested with success PHS8-P (terminal made by MC technologies) 
with 460800 baudrate on UART port (change baudrate with command "AT+IPR=460800").
After power off/on modem did not respont through ASC0 port
nor 115200 not 460800 not any other baudrates (hardware flow control is enable).
Also after power on, yellow led is ligths some seconds and after that goes out.
Whan is was everything good, the green len began flashing. Now it not happens.

If modem connected to PC through USB, I can work with command line:

AT^SDPORT command give default mode: 6 (Application interface is available on ASC0).
But as I wrote below, I cant communicate through ASC0 after set baudrate 460800,
only through USB (via virtual COM port).
I try command AT^SDPORT=3 and try to change baudrate with command AT+IPR=115200 on
virtual COM port (on witch AT^SQPORT? command return "Application") but it did not bring any effect.
After that, I try AT^SDPORT=2 and now, nor ASC0 nor USB not work, so I cant
communicate completely with modem.

I remind after power on, yellow led is ligths some seconds and after that goes out.
When it was everything work good, the green len began flashing. Now this does not happen.
What does that mean?

Can I repair ASC0 port to communicate with modem?

Is it possible to made full factory reset?
Thanks!
