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

...

Parameter log_file_size

Type Text string

Value

If log rotation is enabled, the log_file_size parameter determines the log file size threshold at which the log is automatically rotated.

"unlimited" or "0" (default) - the feature is disabled
"default" - default size is used (4Mb)
<size>[KMG] - size of the current log file in bytes with additional multipliers:
- K - Kilobyte - multiply by 1024
- M - Megabyte - multiply by 1024*1024
- G - Gigabyte - multiply by 1024*1024*1024

Examples:

set OPA0 log_file_size="default"

set

OPA0

log_file_size=10M

Minimum log file size is 64K, maximum is 1G. Setting size less then 64K effectively makes the log file unlimited.

...

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

...

Parameter log_file_size

Type Text string

Value

If the log rotation log mode is enabled this parameter controls switching to next log file based on size of the current file (switching appears on exceeding this size), the log_file_size parameter determines the log file size threshold at which the log is automatically rotated.

"unlimited" or "0" (default) - the feature is disabled
"default" - default size is used (4Mb)
<size>[KMG] - size of the current log file in bytes with additional multipliers:
- K - Kilobyte - multiply by 1024
- M - Megabyte - multiply by 1024*1024
- G - Gigabyte - multiply by 1024*1024*1024

Examples:

set OPA0 log_file_size="default"

set

OPA0

log_file_size=10M

Minimum log file size is 64K, maximum is 1G. Setting size less then 64K effectively makes the log file unlimited.

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"
