Configuring Links for VT over Telnet

The VT over Telnet attachment is an application that uses TCP/IP (Transmission Control Protocol/Internet Protocol) and that enables remote logon to an ASCII host. TCP/IP provides connectivity functions for both local area networks (LAN) and wide area networks (WAN) and includes the ability to route information between LANs and WANs. The major TCP/IP networks—the Internet—use a standardized addressing procedure to ensure that IP addresses are unique and that communication between enterprises is possible.

The VT over Telnet attachment for Z and I Emulator for Windows requires a TCP/IP stack that supports the Windows Sockets Version 1.1 interface. WSOCK32.DLL must be in the Windows system directory or the current path to provide the interface for the stack program and to support the Windows Sockets V1.1 interface.

For the VT over Telnet attachment, you must define the following attachment parameters.
  • Host Name or IP Address (mandatory)
  • Port Number (optional)
  • Terminal ID (optional)
  • Auto-reconnect (optional)
Host Name or IP Address
Specify either the alphabetic name of the target host or its numeric IP address.
Host Name
The name of the target host is a string
Host IP Address
The IP address of the target host is in dotted-decimal notation—for example:
Port Number
Specify the decimal number of the target host's Telnet port. The default, 23, is the standard Telnet port.
Terminal ID
The VT emulator and the Telnet server use the terminal ID for negotiating an appropriate connection. Ask your Telnet administrator for your host's correct terminal ID. When the default box is selected, the default values are selected from the Machine Mode, as shown in the following table:
Machine Mode Default Terminal ID
VT340 DEC-VT220
VT100 DEC-VT100
ANSI ansi
If the session is disconnected from the host, and if this box is selected, you will be re-connected automatically.

The default is not selected.
