Configuring the communication port for a serial connection (COM1 or COM2 only)
Communication between the PAX and PC are done through a serial connection, while payment
processing is over TCP/IP. This configuration helps alleviate network traffic, since
communications between the PAX and PC are not over the network. TCP/IP is dynamically
assigned by the router automatically.
