Disconnect Method (IbmTerminal)

In This Topic

Disconnects from the host. If no connection currently exists, this method is ignored. Use the IsConnected property to determine if a connection already exists.

Syntax

Visual Basic (Declaration)

expression.Disconnect()

where expression is a variable that represents a IbmTerminal Object

Remarks

For more about using the Connect method, see:

Handle TLS Authentication

Example

This sample changes an unsecure Telnet Connecion to TLS 1.2. To run this sample, open a non-secure 3270 Telnet session and copy the code into a code module. Then change the host name and port for a secure connection and run the macro.

Visual Basic

Sub setSecurity()
   
   'Make sure the terminal is disconnected before changing settings
    With ThisIbmTerminal
        If .IsConnected = True Then        
            .Disconnect            
        End If
        
        'enter host that supports TLS
        .HostAddress = "yourHost"
        
        .EnableTelnetEncryption = True
        .TLS_SSLVersion = TLSSSLVersionOption_TLS_V1_2
        
        'Specify that the host name in the certificate must match the name of the host you are connecting to
        .TelnetEncryptionVerifyHostName = True
        
        'You may need to set additional properties to connect, depending on your host configuration.
        'For example, you may need to select a set of custom ciphers in the Security Properties dialog box
        'and then specify to use them as shown below
                
        '.TelnetEncryptionStrength = TelnetEncryptionStrengthOption_Custom
        
        'Replace with your secure port
        .port = yourport
        
        'Connect after changing the settings
        .Connect
        
    End With
        
End Sub
