 +==== (36) I want to telnet to the board and run the same menu of options that you see when you run through the serial console. ​ How do I do this? ====
 +
 +After telnet'​ing into the board, you can type the following command (for DM816X products):
 +
 +<​code>  ​
 +   /​opt/​dvr_rdk/​ti816x/​run_mcsenc.sh
 +</​code>​
 +
 +For DM8107 and DM8148 products, the "​ti816x"​ would change to "​ti810x"​ and "​ti814x",​ respectively.

 +
 +==== (37) I want to use serial port 0 for something else besides the console. ​ How do I configure serial port 0 so it no longer outputs the console? ====
 +
 +This can be done by editing the "​console"​ environment variable in u-boot. ​ Currently it is set to:
 +
 +<​code>​
 +   ​console=ttyO0,​115200,​quiet
 +</​code>​
 +
 +You can reroute the console output to the second serial port instead by typing while in the Linux prompt on your target board:
 +
 +<​code>​
 +   ​fw_setenv console=ttyO1,​115200,​quiet
 +</​code>​
 +
 +You also need to edit /​etc/​inittab to keep getty from respawning on ttyO0.

Is this possible to do? ==== 
 + 
 + 
 +Yes. You can use the function tsmux_add_user_table() to support this. This applies to both the EZSDK and the RDK. 
 + 
 + 
 +===== General Troubleshooting ​ ===== 
 + 
 + 
 +==== Capturing Packet Stream with Wireshark ==== 
 + 
 + 
 +1) Download and install [[http://​www.wireshark.org|Wireshark ]]and associated programs to enable live stream capture on the PC you already use VLC Media Player. A Restart will be required once installation is complete. 
 + 
 + 
 +2) Set encoder for RTP/RTSP transfer and begin encoding as described in your product'​s manual. 
 + 
 + 
 +3) Open Wireshark. Double click the "​Ethernet"​ near the center of the window to automatically begin capture. 
 +

 + 
 + 
 +4) Open VLC Media Player on the Same PC and begin Streaming RTSP as described in your product'​s manual. 
 + 
 + 
 +5) Allow Stream to capture for 1 minute. Click the Red Stop button on the menu bar of Wireshark. 
 +

 + 
 + 
 +6) Hit <​cntrl+S>​ or the Save button at the top of the window to open a save dialog. Give the file a name of your choice that you will remember.

 + 
 + 
 +7) Attach the saved file to an email and send it to Z3 Technology. 
 + 
 + 
 +====  ==== 
  
-Yes.  You can use the function tsmux_add_user_table() to support this.  This applies to both the EZSDK and the RDK.+==== Z3 Cam Solutions Forgotten Password ====
  
  
 +To reset a forgotten password you will need physical access to the unit.
  
  
 +Create a file called **z3passreset ** on an empty SD Card or USB flash drive; insert the SD Card or USB flash drive and power cycle the unit to reset the password to nothing.
