--------------------------------------------------------------------------------------
Is the device's IP: CM+IP=? (Enter)

Example: The device answers CM+IP=192.168.0.1 (Enter)
------------------------------------------------------------

Set IP to 192.160.4.5, serial input CM+IP=192.160.4.5 (Enter)

Query the port of this device: CM+PORT=? (Enter)
Example: The device answers CM+PORT=8253 (Enter)

Reset port to 8255, enter the command CM+PORT=8255 (Enter)
