Scenario 3: Connecting a serial device to a wireless network

This scenario explains how to connect a serial device to a wireless network, enabling serial traffic to be sent to a remote host via TCP/IP.

Overview

In this scenario, the M111 enables a point-of-sale terminal to exchange traffic with a remote host. In addition to providing the connection to a wireless network, the M111 also converts traffic between serial and TCP/IP.

This scenario assumes that:

The M111 is in its factory-default state.

A DHCP server is operating on the private network, assigning addresses on the subnet 192.168.5.0

The MSM AP is operating in autonomous mode in its factory default configuration. (As such, it obtains an IP address of 5.25 from the DHCP server and creates a wireless network call HP ProCurve.) Install the MSM AP as described in its Quickstart.

The remote host is operating as a TCP client.
