User guide

A break sequence is a user-defined combination of characters that can be sent as a command to
a target device during an SSH Passthrough or Avocent Session Viewer session. A break
sequence is sent when the corresponding escape key sequence is typed by the user. The
DSView software supports ASCII and UTF-8 characters and special break keys. Only the user
with read/write access to the SSH session can send a break sequence to a target device.
You can configure up to 10 break sequences to be used in SSH Passthrough sessions.
The following special break keys are supported:
