TTY ·Port properties sheet

Most nY-port properties can be changed only for ECS local ports, which are RS232C ports on the ECS selVer. For other types of ports, only certain properties apply.

If the workstation uses a pseudo port to a VAX on an XNS network, changes to the property sheet are ignored.

Table 2-1 shows which properties are configura-ble for each port type .

port, you can use manual dialing or autodialing (auto dialing requires you to type modem dialing commands in the emulation window). Dialing is described in the section titled "Starting a session:

workstation emulation" later in this chapter.

All properties selected on the property sheet are retained until changed or until the icon is deleted. Figures 2-3 through 2-5 illustrate the property sheets that display for the three port types: CIU ports, ECS local ports, and workstation local ports. You can refer to these figures as you read the following descriptions:

Icon Name

Used to change the name of the TrY-Port icon on the desktop. This property allows you to uniquely name each port icon. The name can be between 1 and 100 characters long. The first few characters appear on the face of the icon on the desktop.

Port Name

Displays, in read-only format, the name given to the port in the Clearinghouse service.

Phone Number

Specifies the full phone number to be dialed for the connection. For a workstation local port, this item should be left blank.

If no phone number is entered and the port is available, the emulator unconditionally opens the window. This is useful for the workstation local port, which uses manual dialing or autodialing (you enter modem dialing commands in the emulation window).

Duplexity

Designates whether communication can occur in both directions simultaneously ([Full]) or in one direction at a time ([Half]). local port. The communication hardware used in the TTY connection determines what values are legal, as well as whether or not they are electronically changeable.

Note: The workstation only supports ISO 646 7-bit ASCII character codes. This property governs the physical length of the character on the transmission line and not the size of the character set supported.

Parity

Designates the method used to check that data is not garbled in transmission. This property cannot be changed for C1U ports. It can be set to [None], [Even], [Odd], [One], or [Zero] for an ECS or workstation local port.

Line Speed

Specifies the rate at which data passes to and from the host computer (also known as baud rate). This property is read-only for a C1U port, and can be set to 50, 75, 110, 134.5, 150, 300, 600, 1200, 2400, 3600, 4800, 7200, 9600, and 19200 baud with a popup menu for a workstation or ECS local port. In addition to these baud rates, the ECS local

Although rates above 9600 baud display on this menu, they are not supported at this time. The communications hardware used in the TIY connection determines what values are legal, as well as whether or not they are electronically changeable. A rate of 1200 baud is recommended.

XONIXOFF Method

Allows you to specify whether the port is to use flow control or not, and which method it will use. The two types of flow control are [Overflowl and [Line-by-Linel.

Note: If you select a type of flow control, first ensure that the host computer accepts and uses the specified type. Otherwise, you may experience unpredictable results. For example, the system can appear to stop processing as it waits for an XON that never
