Options for Accessing the Digi Passport Ports
Chapter 1 Introduction 23
Port Escape Menu
Port escape is the ability to escape from a port without disconnecting. In
port escape mode, a menu of options is displayed, for example, to power
the connected device on or off, send messages to port users, or close the
current connection to the port. Port escape is available in main sessions as
well as sniff sessions. Every connection method accommodates port
escape. Configure the escape sequence per port. To configure the port
escape sequence, follow these steps.
1. Serial Port > Configuration > port number or All.
2. Host mode configuration > port escape sequence: enter a letter for
the Port escape sequence. The default is <Ctrl> z.
3. Click Save to flash and continue with other configurations or click
Save & apply for the changes to take effect.
The port escape menu is automatically started if there is one active ses-
sion to the port established.
4. Enter the port escape sequence that was configured in step 2.
Port Escape Sequences
The following table describes the fields and the operations for the port
escape feature. The fields displayed are those allowed by permissions.
By entering a port escape sequence twice, it is directly transmitted once to
the connected device. If the escape sequence is entered twice within 1/2
second, the port escape menu will not open.
