 There are two different Multitech Conduit firmware versions: mLinux and AEP.
 The AEP version comes with a web-interface and IBM Node-RED pre-installed.
 The mLinux version provides an open Linux development environment and is
 recommended when complete (firmware) control is preferred.
 
-If you don't know the firmware version, here are a couple of ways to tell
-them apart:
-
-1. When logging in via the serial port behind the Multitech logo cover, they
-   display the type of box they are.
-2. The AEP model ships with the default login/password as admin/admin.  The 
-   mLinux version uses root/root.
