Interactive Connections Using the MSS
5 - 4
5.2.1.2 Local Switch
If your terminal does not have a Break key, you can configure a local break switch key with the
Change Local Switch
command.
Figure 5-7: Defining a Local Switch
5.2.1.3 Backward and Forward Switches
The Backward and Forward commands, when entered in local mode, allow users to navigate
through current sessions. The Change Backward Switch and Change Forward Switch commands
define keys that can be used to switch sessions without returning to local mode. The MSS
intercepts and processes these switch keys; it does not pass them to the remote host.
No backward or forward switch keys are enabled by default. They must be explicitly defined
using the commands in Figure 5-8. To specify a control character, precede it with a carat (^).
Figure 5-8: Defining Switches
A user’s open sessions can be thought of as a list from the earliest to the most recently created.
Forward refers to a more recent connection, while backward refers to a session started earlier. The
list is also circular; going forward from the most recently created session takes you to the earliest
session, and going backward from the earliest session resumes the most recent session. For
example, user Bob connects to host Thor. He then breaks to local mode and connects to host Duff.
After working, he breaks and connects to host Conan. His session list, shown with the Show
Session
command, would be:
1. Thor
2. Duff
3. Conan
In the example, Conan is the current session. The current session is either the session to which a
user is currently connected, or the last session the user was in before entering local mode.
If Bob presses the backward key while working in Conan, he will resume his session on Duff. If he
presses the forward key while working in Conan, he will move to his session on Thor.
5.2.1.4 Disconnect and Resume
Users need a method of controlling and disconnecting sessions from local mode. For example, if a
session on a remote host freezes or hangs while executing code, the user can exit the session using
the Break key, then terminate the connection by entering the Disconnect command at the Local
prompt. A user may resume a session after returning to local mode by entering the Resume
command. Both commands can affect any active sessions, not just the current session.
5.2.1.5 Session Limits
The number of active session a user can have on the MSS is limited by three factors: available
server memory resources, a server-wide limit, and a port-specific limit.
The absolute maximum number of sessions for the MSS is eight. To reduce the limit further, enter
the Change Session Limit command followed by a number from one to seven.
