General Description
Each peripheral device of CHARON-AXP offers a one- (OPA0) or two-port serial console, depending on the specified HP Alpha model.
The AlphaServer DS10, AlphaServer DS10L, AlphaServer DS15, AlphaServer 400, AlphaServer 800, AlphaServer 1000 and AlphaServer 1000A has an additional on-board serial line controller providing a serial line TTA0.
The regular console is already preloaded, so you need to specify just its mapping to the host resources, for example:
load physical_serial_line OPA0 line="COM1:" |
In case of the TTA0 console the mapping looks like that:
|
The first line specifies a mapping to some TCP/IP host port ("10000" in this example), while the second line connects this mapping (TTA0) to the on-board serial line controller having the name "COM2" in CHARON environment.
Refer to this section for details of mapping.

Mapping Serial line controllers to system resources
Types of serial line mapping
...
This type of mapping associates a COM port on a host system with an emulated HP Alpha serial line controller virtual "line".
The COM port can be a physical hardware port or a logical COM port.
...
Example:
load physical_serial_line TTA0 |
physical_serial_line
...
A defined COM port on a host system in the form of "\\.\COMn" (or "COM<n>:")
Example:
set OPA0 line="\\.\COM1" |
...
Forces the baud rate of the corresponding COM port to be a specified value.
The variety of supported values depends on the underlying physical communication resource (COM port). The most widely used values are: 300, 1200, 9600, 19200, 38400.
Example:
set OPA0 baud=38400 |
...
Specifies what byte sequences received over the physical serial line will trigger a HALT command.
This parameter works only for the console line (for the one UART line and "line[3]" of QUART).
Specify the following values: "Crtl-P", "Break" or "none" ("none" disables triggering a HALT condition).
Example:
set OPA0 break_on="Crtl-P" |
The default value is "Break" for line 3 of QUART and "none" for other lines.
...
Specifies what byte sequences received over the physical serial line will trigger a STOP condition. The STOP condition causes CHARON-AXP to exit.
Specify the one of the following values: “F6” or “none” ("none" disables triggering a STOP condition).
Example:
set OPA0 stop_on="F6" |
The default value is "none".
Setting "F6" triggers the STOP condition upon receipt of the "<ESC>[17~" sequence. Terminals usually send these sequences by pressing the F6 button
...
A string specifying a file name to store the content of the console sessions or a directory where the log files for each individual session will be stored.
If an existing directory is specified, CHARON-AXP automatically enables creation of individual log files, one for each session using the same scheme as used for the generation of the rotating log files. If the "log" parameter is omitted, CHARON-AXP does not create a console log.
Examples:
set OPA0 log=”log.txt” |
.
set OPA0 log=”C:\Charon\Logs” |
Example of mapping a console line to a host physical serial line:
|
virtual_serial_line
...
A remote host’s IP address or hostname (and optionally a remote TCP/IP port number) for the virtual serial line connection. If omitted, the virtual serial line does not initiate a connection to the remote host and will listen for incoming connection requests.
Specify the value in the following form:
set OPA0 host="<host-name>[:<port-no>]" |
If the "<port-no>" is not specified, the virtual serial line uses the TCP/IP port number specified by the "port" parameter (see below).
...
The TCP/IP port number for the virtual serial line. A virtual serial line always listens on this port for incoming connection requests.
...
An application (a terminal emulator is assumed in most cases) to be started on initialization of this serial line emulation. The specified application startup string may contain all required parameters.
Example:
set OPA application = "putty.exe -load OPA0" |
In this example the terminal emulator application: "putty" is started with the parameters "-load OPA0" telling it to load a specific saved session named "OPA0", (created separately) from the host registry.
The "application" parameter is often combined with a "port" parameter:
set TTA0 port = 10003 application = "putty.exe -load TTA1" |
...
Specifies what byte sequences received over a virtual serial line triggers a HALT command.
Specify one of the following values: "Crtl-P", "Break" or "none" to disable triggering a HALT condition. The commands are case insensitive.
Example:
set OPA0 break_on="Crtl-P" |
The default value is "Break" for line 3 of QUART and "none" for other lines.
...
Specifies what byte sequences received over the virtual serial line will trigger a STOP condition. The STOP condition causes CHARON-AXP to exit.
Specify one of the following values: “F6” or “none” ("none" disables triggering a STOP condition). The commands are case insensitive.
Example:
set OPA0 stop_on="F6" |
The default value is "none".
Setting "F6" triggers the STOP condition upon receipt of the "<ESC>[17~" sequence.
...
A string specifying the filename to store the content of the console sessions or a directory where log files for each individual session will be stored.
If an existing directory is specified, CHARON-AXP automatically enables the creation of individual log files, one for each session using the same scheme as used for the generation of the rotating log files. If the "log" parameter is omitted, CHARON-AXP does not create any console log.
Examples:
set OPA0 log=”log.txt” |
set OPA0 log=”C:\Charon\Logs” |
Example of mapping a console line to a host TCP/IP port 10003 and starting a "Putty" terminal emulator with a configuration "OPA" directing it to connect to the port 10003:

Notes on "virtual_serial_line" options:
Use the combination of "port" and "host" parameters as follows to connect a 3rd party terminal emulator or similar program.
load virtual_serial_line TTA0 host="192.168.1.1" port=10000 |
In this example CHARON-AXP connects to port 10000 of a host with TCP/IP address "192.168.1.1" and at the same time it accepts connections on local port 10000.
It is possible to specify a port on a remote host (note that CHARON always acts as a server). The syntax is:
load virtual_serial_line TTA0 host="192.168.1.1:20000" port=10000 |
In this example CHARON-AXP accepts connection on local port 10000 and connects to remote port 20000 of a host with TCP/IP address "192.168.1.1"
Note: the examples above are mainly used for inter-CHARON communications. They are used to connect CHARON-AXP to an application that communicates to CHARON-AXP as described below.
Example of two CHARON systems connected to each other:
On host "A":
load virtual_serial_line TTA0 port=5500 host="B" |
On host "B":
load virtual_serial_line TTA0 port=5500 host="A" |
...
Value format: "pci_<N>" When specified, the bus configuration parameter tells the CHARON-AXP software the virtual PCI bus to which virtual HP Alpha system shall connect a certain virtual PCI adapter. By default the bus configuration parameter is not specified. If the bus configuration parameter is not specified, CHARON-AXP software connects the virtual PCI adapter to the first available virtual PCI bus. Example:
| |||
| device | Numeric | When specified, the device configuration parameter specifies position of a virtual PCI adapter on virtual PCI bus. By default the device configuration parameter is not specified. If the device configuration parameter is not specified, the CHARON software connects the virtual PCI adapter at the first available position of the virtual PCI bus. Example:
