CHAPTER 7: Operation
7.1.1.2 Disconnecting Ports
There are three different methods for disconnecting ports: the Resident
Disconnect, the Third-Party Disconnect, and the No Activity Timeout. If the
Timeout feature has been enabled, a No Activity Timeout will disconnect resident
ports or third-party ports.
NOTE
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 for 0.5 seconds and then held high.
1.
Resident Disconnect:
Disconnects your resident port from another port. For
example, if you are communicating through Port 3, and Port 3 is connected to
Port 4, a Resident Disconnect would be used to disassociate the two ports. The
Serial Console Port Manager offers two different Resident Disconnect
command formats: the Three-Character Format and the One-Character
Format (see
Section 5.5.3
):
a)
Three Characters (default):
Takes the form “
[ Enter]
LLL
[Enter]
”, where
L
is the selected Logoff Character. The Default Resident Disconnect
Sequence is
[Enter]
+++
[Enter]
.
b)
One Character:
When the One Character Disconnect Sequence is
selected, simply enter the selected Logoff Character once. The default
Logoff Character is the plus sign (
+
). Note that it is not necessary to enter
a carriage return before or after the Logoff Character.
c) If the default Resident Disconnect Sequence is not compatible with your
application, both the command format and the Logoff Character can be
redefined using the Port Configuration menus, as described in
Section 5.5.3
.
