Black Box Console Server user guide 109
Configuring Break Pass Through
The Console Server will not send break signals on power cycles. It is also configured
not to allow break signals to be sent through to attached devices by default. However,
some administrators may wish to be able to send the break signal i.e. to take a Sun
Solaris system to the Open Boot prompt.
To enable this feature, please use the following CLI command to enable/disable
proprietary inband SSH break signal processing as well as existing Reverse Telnet
break signal.
# set server break <on/off>
# save
The OEM mode flag 0x0010 will be set/reset based upon this command.
Alternatively, you can enable/disable this feature but using "set server OEM_mode".
A break signal is generated on a specific serial port only when the server's break
option is enabled and the user has typed the exact break string over a reverse SSH
connection.
The OEM mode flag 0x0010 will be set/reset based upon this command.
Alternatively, you can enable/disable this feature but using "set server OEM_mode".
For SSH, the default break signal is ' ~ break', where ~ is tilde. To change the SSH
break signal, use the following command:
# set server sshbreakstring <8-characters>
Note A terminal emulator must be used that is capable of sending the break signal.
