Most models emulated by Charon-PAR have two serial lines (LDev 20 and 21). One of these emulated lines is mapped to the serial console, the other to a second serial port. Some models may have more serial lines. Please refer to Emulated Model Hardware Configuration Details for more information. This section provides an overview of the serial line configuration. Please also refer to the Configuration File Reference.

Configuration Parameters Overview

...

The following table shows the device and configuration paths used for the two serial lines:

Serial port configuration options are specified using the following syntax:

Serial port configuration options are specified using the following syntax:

 If If the Super/IO module has been loaded, there are two additional serial lines. In the configuration, they are identified by 

• superio_001.uart0 and
• superio_001.uart1.

The basic configuration options are the same as for the default serial lines.

...

A serial port has three configuration options:The most important configuration options are listed below. For additional parameters and more detailed information, please refer to the Configuration File Reference.

The configuration file templates contain the following default configurations:

If not done so already during the installation, copy the provided PuTTY profiles to the correct directory on the host system. See See Post-Installation Tasks in  Charon-PAR Software Installation#PARSoftwareInstallation-Post-InstallationTasksInstallation.

Accessing Emulated Charon-PAR/PA3 Systems via Terminal Emulation

Charon-PA3 guest systems can be accessed directly from the Linux emulator host using either the PuTTY or xhpterm terminal emulator described below, both of which run directly on the Linux host desktop, or by simply using the telnet command. Each has limitations, however. Neither terminal emulator provides a reliable way to paste multiple lines of text into :EDITOR , for example.
Once the network of the Charon-PAR/PA3 guest system has been configured configured, it may be preferable to connect to the emulated system from a networked PC using any of the robust commercially-available terminal emulators.

...

• charon-host: IP address or hostname of the Charon-PAR host system on which the emulator runs
• console-tcp-port: The TCP port configured for the serial console port in the configuration file of the emulated PA3 system

  Please note: Line-editing is very limited. To delete a character on the command-line, use CTRL+BACKSPACE. Note that the deleted character will still be visible until it is overwritten. Block-mode applications are not supported.

...

The PuTTY terminal emulator is the preferred method to use as the Charon-PAR/PA3 console. It does not, however, support HP the terminal escape sequences used by the legacy hardware, so any inverse or highlighted text codes will be ignored, and block mode applications cannot be run. Using PuTTY in telnet mode (as supplied) allows use of the Break key. PuTTY supports copy and paste. To copy text to the clipboard, just select it with the left mouse button (this automatically copies the selection to the clipboard). To paste the clipboard into a PuTTY window, use Shift-Ins . Unfortunately, PuTTY cannot be used to reliably paste large blocks of text (even with MPE type-ahead enabled), as data overruns can easily occur.

By default, the emulator configuration is set up to start PuTTY on the console port with the commanda command similar to the following example:

serial.uart0.device.command="putty -load HPAPAR-Telnet" (default port 30000). 

...

The image below shows a PuTTY terminal window connected to the guest MPE/iX system console:

Please note: Line-editing is very limited. To delete a character on the command-line, use BACKSPACE. Note that the deleted character will still be visible until it is overwritten. Block-mode applications are not supported.

Using xhpterm

The xhpterm terminal emulation (an X Windows version of freevt3k ) does not support many terminal escape sequences used by historic HP3000 hardwarePA-RISC hardware for MPE/iX, but it can be used to run block-mode applications. It must be used on a serial line set up for raw mode.

...

The following image shows an xhpterm window connected to the second serial line of an emulated MPE/iX system (running NMMGR):

Working without Block-Mode Enter key

If working without a block-mode Enter key, you can navigate using the function keys of your keyboard. They correspond to the selection fields at the bottom of the screen.

For example, in the above window,

• F1 would correspond to Open Config,
• F8 would correspond to Exit Program.

Using Different Fonts

The default command-line to start xhpterm is:  $ xhpterm -port 30000 -clean -font 10x20

...

 When Please note: When using xhpterm , avoid resizing the window - it can result in input and output fields in block-mode programs being misaligned. Changing the screen font will change the window size automatically, without causing this problem.

Accessing Emulated Charon-PAR/PA9 Systems via Terminal Emulation

Using Non-Graphical Telnet Client

In the absence of a graphical user environment, terminal emulators such as PuTTY and xhpterm cannot be used. In such cases, you can use the telnet command on the Charon host or from a remote system (if the serial line configuration permits it) to access the serial console port of the emulated PA3 system.

...

• charon-host: IP address or hostname of the Charon-PAR host system on which the emulator runs
• console-tcp-port: The TCP port configured for the serial console port in the configuration file of the emulated PA3 system

  Please note: To make character deletion via the BACKSPACE key work on the command-line of HP-UX, you may have to enter the command$ stty erase <backspace-key> (and add it to your shell startup file, e.g., $HOME/.profile).).

Using PuTTY

Stromasys provides preconfigured PuTTY profiles to access the serial console of an HP-UX system running on Charon-PAR. PuTTY does not support all control characters used by HP-UX, but many utilities (e.g., SAM) will work with some restrictions.

By default, the emulator configuration is set up to start PuTTY on the console port with the commanda command similar to the following example: 
   serial.uart0.device.command="putty -load HPAPAR-Telnet-VT100".

To start an terminal emulator manually, perform the following steps:

 Instead Instead of PuTTY, you can also use the standard telnet command on your local or remote Linux system (telnet <charon-par-host> <port>). However, Stromasys does not provide profiles for this. To make character deletion via the BACKSPACE key work on the command-line of HP-UX, you may have to use the command $ stty erase <backspace-key>.

Additional configuration steps to improve the behavior of the terminal emulation:

 Additional Additional information: Cannot get correct line drawing on Linux/UNIX with Putty.

Accessing the Emulated System Console from a Remote System

 Please Please note:

• The serial line port configuration must allow the remote connection.
• intermediate firewalls must allow the ports used.

...

• There can be only one connection to an emulated serial line at one time.

The following two options provide two examples of how to connect to the console of an emulated system from a remote system.

...

Even though a plain telnet connection can be used to connect to the emulated system's console, this plaintext connection may create security problems. As an alternative, you can tunnel a terminal emulation through an SSH tunnel provided X11 is active on the emulator host and the remote system.

 Any Please note: Any intermediate firewall must permit the port used for SSH (default 22).
