Reset EHS6T modem to defaults. | Telit Cinterion IoT Developer Community

Previously I would get URC's ^SYSREADY, ^SYSLOADING output messages via ASC0 on power up. However I no longer get these, not sure at which stage I lost them. If I enter any AT commands via HyperTerminal connected to ASC0 I get no response from the EHS6T. If I run a MIDlet from Netbeans, with stdout previously redirected to ASC0, I will get the expected messages via HperTerminal. Entering AT&F does not appear to reset things back to square one - the EHS6T is not echoing back the characters. Not able to run AT^SJAM=4 to see if there are any MIDlets runnings. The impression is the default MIDlet for responding to AT commands installed on the modem is not responding or not started.
Any help on getting back to the original configuration would be appreciated, so I can enter AT commands via HyperTerminal.
Hello,
Please try other interfaces then ASC0.
If you have redirected system out to ASC0 you will not be able to issue any commands on that interface.
If other interfaces are not available maybe the problem is not in the module but PC software. Have you tried to connect the module to another PC?
Please try to turn the OJMEE off (you will find it in the system tray) and restart the module. If nothing helps, restart the computer eventually.
Best regards,

I am unable to connect to the EHS6T via the USB port via HyperTerminal to issue AT commands. Tried on another PC, but no difference. Another option may be to redirect via sending a AT command via a MIDlet, but unsure the required format where you have " within the at.send("AT^SCFG="Userware/stdout","asc1"\r"). Any help would be appreciated.
Sorted, added \ before the internal", and thus able to reset the modem within a MIDlet, so now stdout not re-directed to ASC0.
Hello,
So it was a system out issue.
You can watch the System.out on ASC1 - there are pins available - you can find the location in HW description.
The following settings would be required to use the ASC1 interface:
AT^SCFG="Gpio/mode/ASC1","std" to enable ASC1 interface (reserve common lines for ASC1)
AT^SCFG="Serial/Interface/Allocation","1" to request serial interface allocation. The last command is effective after restart.
