The Vconsole represents the serial console device of a Charon-SSP/4V instance. To view or change the current virtual machine console configuration, select Vconsole in the Device column of the left-hand pane of the configuration Settings window. This opens the Vconsole configuration window, shown below.
...
The emulated terminal type can have one of four values as described below. Use the Type drop-down list to set the value.
TCP raw: Configure configure the console device as a network device (TCP socket) without any protocol enabled.
Telnet: Configure configure the console device as a network device (TCP socket) with the telnet protocol enabled.
Physical: Configure configure the console device as physical terminal directly attached to the host system. <check how this is relevant for AWS>For an AWS instance, this could be a virtual serial line provided by a serial line server (terminal server).
Disabled: Disable disable the virtual console device entirely.

Vconsole Network

Configuration
When configuring a network console device, the user can select one of two modes:
...
Network Vconsole Configuration Options and their Functions
Port:
This option specifies the TCP/IP port to use when listening for incoming console client connections. A different port must be specified for each network console and serial port used on the same Charon-SSP host system.
Using a port that is already in use results in the following error messages in the virtual machine log file similar to the following.
To access the console of a guest system across the network without, make sure the port configured for the console is permitted by any intermediate firewalls and/or security groups. If using the built-in console function of the Charon Manager in combination with the Charon Manager SSH tunnel, the console port is redirected through this SSH tunnel.
Console:
For Charon-SSP AWS, the value of this parameter is fixed to Built-in. The built-in console is displayed and accessible from the Console tab in the Charon Manager. The console process listens on TCP port 9000 by default.
Log:
When this box is checked, Charon-SSP writes a console log file.
Please note: the log file configured here is separate from the file the Charon-SSP Manager uses to cache the console output for the built-in serial console of the Charon-SSP Manager.

TTYA Configuration
To view or change the current virtual machine console configuration, select TTYA in the Device column of the left-hand pane of the configuration window. This opens the TTYA configuration window, shown below. In this example, TTYA is disabled.
...
On Charon-SSP/4U and Charon-SSP/4M, TTYA can be configured as the serial console or, if the graphical device is configured to be the system console, TTYA can be used as a normal serial line. On Charon-SSP/4V systems, it can only be used as a normal serial line.
The emulated terminal type can have one of four values as described below. Use the Type drop-down list to set the value.
TCP raw: Configure configure the console device as a network device (TCP socket) without any protocol enabled.
Telnet: Configure configure the console device as a network device (TCP socket) with the telnet protocol enabled.
Physical: Configure configure the console device as physical terminal directly attached to the host system. <check how this is relevant for AWS> For an AWS instance, this could be a virtual serial line provided by a serial line server (terminal server)
Disabled: Disable cisable the virtual console device entirely.
The following sections describe the specific configuration details of physical and network consoles.

TTYA Network Configuration
When configuring a network console device, the user can select one of two modes:
TCP raw (serial line without protocol), or
Telnet (serial line with telnet protocol support).
Please note that TTYA cannot be used as the serial system console for Charon-SSP/4V systems. Such systems must use the Vconsole device.

To view or change the virtual machine TTYB configuration, select TTYB in the Device column of the left-hand pane of the configuration window. The virtual TTYB serial device can be configured as both a physical or network connected device. The configuration of this device is very similar to TTYA. For further details related to configuring this device, consult the section TTYA Configuration.
