8.1.1.2. 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 is enabled, a
No Activity Timeout will disconnect resident ports or
third party ports.
Note: When Any-to-Any Mode, Buffer Mode, or
Passive Mode are selected, Option 74 in the Port
Parameters Menu determines how the DTR signal
will react when the port disconnects. The DTR
signal can either be held low, held high, or pulsed
and then held high.
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.
The APS offers two different Resident Disconnect
command formats; the One Character Format and the Three
Character Format (for more information, please refer to
Section 5.5.3.):
a) One Character (Default): When the One Character
Disconnect Sequence is selected, simply enter the
selected Logoff Character once (Default = ^X ([Ctrl]
plus [X])). Note that it is not necessary to enter a
carriage return before or after the Logoff Character.
b) Three Characters: Uses the format
“[Enter]LLL[Enter]”, where L is the selected Logoff
Character. For example, if the Logoff Character is
defined as "+", then the three character disconnect
sequence would be [Enter]+++[Enter].
c) If the default Resident Disconnect Sequence is not
compatible with your application, both the command
format and Logoff Character can be redefined via the
Port Configuration menus, as described in Section 5.5.
