Type

Function

physical_serial_line

This type of mapping associates some TTY port on host system with an emulated HP Alpha serial line controller virtual "line".

The TTY port can be physical hardware port or a logical TTY port.

virtual_serial_line

This type of mapping associates a network connection on the host system with an emulated HP Alpha serial line controller virtual "line"

operator_console

This type of mapping associates the current TTY console with the OPA0 console port (if CHARON-AXP does not run as service)

Example:

load physical_serial_line TTA0

physical_serial_line

line

Description

Parameter line

Type

line Text string

Value

A defined TTY port on host system:

Syntax	Description
"/dev/tty<N>"	Virtual serial lines
"/dev/ttyS<N>"	Onboard serial lines
"/dev/ttyUSB<N>"	Modem or USB serial lines adapters
"/dev/tty<XXX>"	Proprietary (depending on a driver) devices such as DIGI or MOXA cards

Note
A specific account for running CHARON ("charon") does not allow usage of physical consoles "`/dev/tty<N>`" as CHARON consoles. If you plan to map CHARON console to "`/dev/tty<N>`" use only "root" account for CHARON running.

baud

Parameter baud

Type Numeric

Value

Forces the baud rate of the corresponding TTY port to a specified value.The variety of supported values depends on the underlying physical communication resource (TTY port). The most widely used values are: 300, 1200, 9600, 19200, 38400.

Example:

set OPA0 baud=38400

break_on

Parameter break_on

Type Text string

Value

Specifies what byte sequences received over the physical serial line will trigger a HALT command.

This parameter works only for the console line.

Specify the following values: "CrtlCtrl-P" , "Break" or "none" ("none" disables triggering a HALT condition).

Note

If your guest operating system is OpenVMS in addition to "none" setting you have to set a specific console parameter "controlp" to "off" in the following way:

>>> set controlp off
>>> power off

The second line is to preserve the ROM settings.

Example:

set OPA0 break_on="CrtlCtrl-P"

The default value is "Break".

This parameter can be specified only for COM1 (OPA0) console

stop_on

Parameter stop_on

Type Text string

Value

Specifies what byte sequences received over the physical serial line will trigger a STOP condition. The STOP condition causes CHARON-AXP to exit.

Specify either “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

This parameter can be specified only for COM1 (OPA0) console

log

Parameter log

Type Text string

Value

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”

.

"log.txt"

set OPA0 log=

”

"/Charon/Logs

”

"

Note
Only existing directory can be used as a value of the "log" parameter.

virtual_serial_line

host

Parameter host

Type

Description

Text string

Value

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).

port

Parameter	port
Type	Numeric
Value	The TCP/IP port number for the virtual serial line. A virtual serial line always listens on this port for incoming connection requests. If multiple virtualized machines are running on a server, ensure the port number is unique across the platform.

break_on

Parameter break_on

Type Text string

Value

Specifies what byte sequences received over a virtual serial line triggers a HALT command.

Specify one of the following values: "CrtlCtrl-P" , "Break" or "none" to disable triggering a HALT condition. The commands are case insensitive.

Note

If your guest operating system is OpenVMS in addition to "none" setting you have to set a specific console parameter "controlp" to "off" in the following way:

>>> set controlp off
>>> power off

The second line is to preserve the ROM settings.

Example:

set OPA0 break_on="CrtlCtrl-P"

The default value is "Break".

This parameter can be specified only for COM1 (OPA0) console

stop_on

Parameter stop_on

Type Text string

Value

Specifies what byte sequences received over the virtual serial line will trigger a STOP condition. The STOP condition causes CHARON-AXP to exit.

Specify either “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.

This parameter can be specified only for COM1 (OPA0) console

log

Parameter log

Type Text string

Value

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"log.txt”txt"

set OPA0 log=

”

"/Charon/Logs

”

"

Note
Only existing directory can be used as a value of the "log" parameter.

Example

...

Mapping a console line to a host TCP/IP port 10003:
`load virtual_serial_line OPA0 port=10003`
Div
class pagebreak

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"

"ttyY" notation specifics

Note that the "ttyY" notation can have different forms depending on the nature of the device used:

Mapping Type Commentary

"/dev/tty<N>"

where N is from 0 to 11

Linux virtual tty

Those tty devices must be free from the Linux "getty/mgetty" and similar programs (specified in "/etc/inittab")

Example:

"/dev/tty1"

"/dev/ttyS<N>"

where N is a number

Onboard serial lines

Example:

"/dev/ttyS1"

"/dev/tty<XXX>"

where XXX is a complex letter/number notation

Proprietary (depending on a driver) devices

Example for a first port of a MOXA card:

"/dev/ttyR01"

Example for a first port of a DIGI card:

"/dev/ttyaa"

"/dev/ttyUSB<N>"

where N is a number

Modem or USB serial lines adapters

Example:

"/dev/ttyUSB1"
