ADD WINDOW
If you specify CALLER ip-address, the window is assigned only to a
session initiated by that IP address. If you omit the CALLER, the window
may be used by any session. When a session is established, the TN3270e
server looks first for an available window with the caller’s address. If no
window is available, it looks for any available window without a CALLER
address.
ip-address
is a TCP/IP address in dotted decimal form.
port-num
is an integer between 0 and 65,534.
If you specify PORT port-num and CALLER, the window is restricted to a
session originating from the specified port on the client. This feature is
intended for terminal servers that always use the same port number for an
attached terminal.
Considerations
The TN3270e server supports both generic and specific device pools. When a window
is added to the server, and if the window is not assigned a specific IP address or
device name, the terminal or printer device being defined is placed into a generic pool.
Separate pools exist for terminals and printers.
When a client connects and specifies a specific IP address, the server searches for an
available window that matches the specified IP address. If a matching window is not
found, the next available entry in the appropriate generic pool is returned. If no
windows are available, an error message is returned.
When a client connects and specifies a specific device name, the server searches for
an available window that matches the specified device name. If no matching window is
found, a device-type reject message is displayed to the user. For information about
device-type reject messages, see Section B, Client Messages.
A client also has the option to connect as a printer associated with a specific terminal.
The server defines this device as an ASSOCIATE device name, and the client
identifies the desired printer using an ASSOCIATE device-name command.
