If I issue an AT+CFUN=1,1 (soft reset) command to an EHS6T modem the connected USB serial port is dropped and I can not open the serial port again with out a power cycle of the EHS6T (hard reset).
Is this normal behavior for the USB serial port interface on the EHS6T modem ?
I get an OK answer from the AT+CFUN=1,1 but after that the modem does not respond to AT commands and there is no ^SYSSTART shown.
If I issue an AT+CFUN=0 (shutdown) I get the OK and ^SHUTDOWN shown fine.
It seems like the AT+CFUN=1,1 is not working properly.
I have firmware revision:
