IBM 243X user manual Using Serial Communications on the Terminal

Operating the Terminal in a Network 3

Communicating Across Subnetworks (UDP Plus) You can install the 2435 terminals and access points in one subnetwork and install the DCS 30X or host in another subnetwork. In this network, you must configure additional network parameters (default router and subnet mask). The next illustration shows the DCS 30X in another subnetwork from the terminals.

Using Serial Communications on the Terminal

The 243X has a serial port to transfer data to and from another device, such as a printer, modem, or PC, using serial communications. Before you can use serial communications, you must perform these steps:

1.Connect the terminal to a serial device or network. For help, see “Connecting to a Serial Device or Network” in Chapter 1.

2.Choose a communications protocol. For help, see the next section, “Choosing a Communications Protocol.”

3.Configure the serial port parameters to allow the terminal to communicate with a host computer or serial device in a wired network. For help configuring the terminal, see Chapter 2.
