Non-transitory storage medium storing plurality of instructions readable by computer of information processing apparatus and information processing apparatus

A non-transitory storage medium storing a plurality of instructions readable by a computer of an information processing apparatus,

• wherein the information processing apparatus comprises a communication interface,
• wherein a plurality of communication ports for communicating with a plurality of devices respectively through the communication interface are set in an operating system of the information processing apparatus, the plurality of communication ports being capable of being associated with the plurality of devices respectively,
• wherein, when executed by the computer, the plurality of instructions cause the information processing apparatus to execute first setup processing of allowing a particular port of the plurality of communication ports to be used by software used for communicating with the particular device through the communication interface, the particular port being associated with the particular device of the plurality of devices, and,
• wherein, when executed by the computer, before the first setup processing is executed, the plurality of instructions cause the information processing apparatus to:
• execute determination processing of determining whether the first setup processing is executable for the particular port or not, and
• when it is determined that the first setup processing is not executable for the particular port in the determination processing, execute second setup processing of setting up the particular port as the communication port for which the first setup processing is executable.
