 * Portable - Applications with low acceleration, e.g. portable devices. Suitable for most situations. MAX Altitude [m]: 12000, MAX Velocity [m/s]: 310, MAX Vertical Velocity [m/s]: 50, Sanity check type: Altitude and Velocity, Max Position Deviation: Medium.
 * Airborne < 1G - Used for applications with a higher dynamic range and vertical acceleration than a passenger car. No 2D position fixes supported. MAX Altitude [m]: 50000, MAX Velocity [m/s]: 100, MAX Vertical Velocity [m/s]: 100, Sanity check type: Altitude, Max Position Deviation: Large

 ### Constraints
 
+If the configuration is invalid the serial port configuration will reset to it's defaults and features may be disabled.
+
 * There must always be a port available to use for MSP
 * There must always be a port available to use for CLI
-* To use a port for a function, the function's corresponding feature must be enabled first.
-e.g. to use GPS enable the GPS feature.
-* If the configuration is invalid the serial port configuration will reset to it's defaults and features may be disabled.
-* If softserial is used be aware that both softserial ports must use the same baudrate.
+* There can only be 1 CLI port.
+* There is a maximum of 2 MSP ports.
+* To use a port for a function, the function's corresponding feature must be also be enabled.
+e.g. after configuring a port for GPS enable the GPS feature.
+* If softserial is used both softserial ports must use the same baudrate.
