Port number:
This is the port ID of each port. Application software will refer to a port by its
port number (ID). Port numbers must be unique; duplicate port numbers are not
allowed. The port ID can range from 0 to 127 as long as it does not overlap
with another port. Generally, you should consider the convenience of
programming when specifying the port number.

This is the transmission (output) buffer allocated in the system for each port.
RxD buffer size:
This is the receiving (input) buffer allocated in the system for each port.
