The Tektronix 4014 Terminal Emulator icon behaves as both a functional icon and a ViewPoint container. This means, in part, that its property and option sheets provide two displays:
(1) a set of properties or options that define the terminal emulator software and (2) a display of the TTY-Port icons that have been moved or copied into the terminal icon.
As a functional icon, the Tektronix 4014 Terminal Emulator icon can be used to configure and run the software associated with it. When you select [Properties] on the property sheet or [Options]
on the option sheet, the properties or options you use to configure the software are displayed.
The terminal icon as a container

When you select [Ports] at the top of either the Tektronix 4014 property or option sheet, the contents of the "container" are displayed: a list of TTY ports. When you start the terminal emulation

software, it interprets this list as the ports to try, in order, until it successfully reaches a host.
The terminal emulator Ports display looks and acts like an unsorted folder; however, only TTY-Port icons can be moved or copied into it. In addition, it functions somewhat differently when viewed through the option sheet rather than the property sheet. Functional differences are described later in this section.
The order of ports within the terminal emulator icon is significant: It is the order in which the terminal emulator will try to use each port to make a connection. You can cause the terminal emulator to try the same port several times by having multiple copies of that port within the terminal container. The emulation software will try each enabled port, in order, either until a connection through one is successful or until all ports have been unsuccessfully tried.
You can enable and disable the port by using the [Enable Port] and [Disable Port] commands in the window's auxiliary menu or the Enabled property on the port's property sheet.
Figure 5-2 shows an example of a terminal emulator icon property sheet displaying the ports contained in the icon. In this example, the terminal emulator will fii'st attempt a connection through the port called 1200 Baud B1. It will then try the same port again to a different host phone number. Then, after skipping B2 and B3, the emulator will try the slower 300 Baud A 1.
Terminal container property sheet operations
Any function that you can perform on port icons outside of the terminal .property sheet Ports display you can also perform within it, such as
<PROP'S>, <COPY>, and <MOVE>. All changes made to the Ports display when shown

through the terminal "container" property sheet are remembered the next time you display the terminal property sheet or open the terminal icon to establish a session.
If you select the [Cancel] command in the property sheet window header, none of the chaQges you made in the container are kept. This means that a port you have moved into the container will be lost. If you use the < MOVE>
key to place a port within the container and then select [Cancel], the emulation software asks you to confirm the [Cancel] operation.
Terminal container option sheet operations
5·6
Changes you make to the contents of the terminal option sheet are in effect only for the current emulation session. For terminal properties and ports to be permanent, they must be changed through the property sheet. Not all container operations can be done through the option sheet, as it is meant only to affect the current session. Table 5-1 describes the behavior of different container operations performed within the terminal icon option sheet.
