Dell Venue Pro - AT Commands while searching for interop unlock

While looking for a hint of interop unlock on a Dell Venue Pro device (running Windows Phone 7), I was working with the Engineering Mode application. One of the capabilities it offers is an AT command execution layer. While follwoing the list of Motorola-based commands, I selected a few that yield actual results.

Command Description Returns
AT+TMSWV Software Version 2250.1800.7720.219[Aug 22 2011-16:41:20]
AT+CGSN ESN value Varies
AT+GMM Phone Model Dell Venue Pro
AT+CBC Battery Charge 2,0
AT+CGMI Manufacturer Dell Inc.
AT+CGMM Model Info Dell Venue Pro
AT+CGMR Revision Info 8650B-SDCAOWZM-225018 1 [Nov 23 2010 22:00:00]
AT+CNUM Phone Number Number Varies, 129
AT+GCAP Capabilities +CGSM, +FCLASS, +DS
AT+CPAS Activity Status 4
AT+CSQ Signal Strength RSSI, FER

These are commands that create instant results. You can also use commands that are more complex and require sequential input - those can be used to send text messages, for example. Coupled with OurCOM.dll these can be used to read various phone information directly from an application that can access interop capabilities.

In order to get to the AT command layer, follow these steps:

  1. Type ##634# in the dialer to unlock the EM application.
  2. Double-tap on the empty part of the grid.
  3. Slide down the hardware keyboard and type qwertyuiop.
  4. Click on Protocol.
  5. Type in *#6336#.
  6. Select TMO.
  7. Select AT_COMMAND.

You can test most of the commands there. I will keep this page as a general reference, and as I find out more commands that work, I will update it.
