TCP API starting port number
TCP API ending port number
Each connection attempt uses the next port number in sequence until the end
port is passed. When this happens the port is set to the start port number.
This current port number in use is retained over a power cycle.
If only the start port number is provided, the end port number will be start port
number + 49 (range of 50).
The default start port number is 1024. The modem will increment the port
number with each connection attempt until it reaches the default end port
number of 65535. Once the modem reaches the end port number it will begin
incrementing the ports again using the start port number of 1024.
