6.1.1.2. Disconnecting Ports

 

There are three different methods for disconnecting ports, the Resident Disconnect, the Third Party Disconnect, and the No Activity Timeout. Providing the Timeout feature has been enabled, a No Activity Timeout will disconnect resident ports or third party ports.

Note:

The DTR signal will drop for approximately 250 ms after a disconnect.

1. Resident Disconnect: Disconnects your resident port from another port. For example, if you are communicating via Port 3, and Port 3 is connected to Port 4, a Resident Disconnect would be used to disassociate the two ports.

a) The default Resident Disconnect Sequence is [Enter]+++[Enter].

b) If the default Resident Disconnect Sequence is not compatible with your application, the Logoff Character can be redefined using the /P (Port Configuration) command. For example, if the Logoff Character is defined as @, the new Resident Disconnect Sequence would be [Enter]@@@[Enter].

2. Third Party Disconnect: The /D command is issued from your resident port to disconnect two third party ports. For example, if your Resident Port is Port 1, a Third Party Disconnect would be used to disconnect Port 3 from Port 4.

a) The /D (Disconnect) command can only be invoked by a port with access to "All" commands.

b) The /D command can specify both connected ports, or either of the two ports. For example, if Port 1 is your resident port, any of the following commands can be used to disconnect Port 3 from Port 4:

/D34 [Enter]

or

/D 3 [Enter]

or

/D 4 [Enter]

3. No Activity Timeout: Providing the Timeout Disconnect feature is enabled at either connected port, the No Activity Timeout can disconnect Resident Ports, or Third Party Ports.

a) To enable the Timeout Feature, invoke the /P command to display the Port Configuration Menu for the desired port. Option 11 enables and defines the Timeout Feature.

b) When the Timeout Feature is enabled, the port will automatically disconnect if no data is received for the defined Timeout Period
