vxWorks kernel shell abilities
<p>I have a car navigation system installed in my car and I figured out that it's running vxWorks 6.9.3. </p>

<p>What I'm trying to achieve is to change some hidden settings of the nav-system. </p>

<p>Small introduction: Nav system have ability to connect to internet via Bluetooth. I setup small web-server the only thing it can do is detect IP address of client. I opened that web-site from head unit browser and detected ip address of head unit. Than I'm able to scan for opened network ports of it.</p>

<p>It turned out that it has 23 port open. And I'm able to telnet there.
It didn't required any password or login and it report operation system info: Windriver vxWorks 6.9.3 </p>

<p>I can run various commands here, inspect filesystem, etc. 
But I don't know how I can change something. I even found the way to transfer files from USB-key from and to device. </p>

<p>I found that all settings which I want to change are stored in .sqlite files. Some of them are gzipped and have .inf file with check-sums. Algorithm of check-sum calculation is proprietary so I can't transfer .sqlite files from device to usb-key, change something, than gzip and calculate new check-sum.  </p>

<p>I think OS can somehow interact with .sqlite files in-memory without ungzip them. 
So, is there any ways to open sqlite shell on device using vxWorks kernel shell? 
If yes, that would be perfect and enough to achieve anything I want. </p>

<p>If this can't be achieved, can somebody give me some advice of what possibilities I have from vxWorks kernel shell? </p>
