Console Parameters
CHARON-AXP console line TTA0 (COM2) has the following parameters:
All the values in the following tables are case insensitive
communication
| Parameter | communication |
|---|---|
| Type | Text string |
| Value |
|
line
| Parameter | line | |
|---|---|---|
| Type | Identifier | |
| Value | This parameter is used to connect a particular serial line mapping interface to the controller. Example:
|
Example
set COM2 communication="binary" |
...
| Type | Function |
|---|---|
| physical_serial_line | 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. |
| 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" |
Example:
load physical_serial_line TTA0 |
...
| Parameter | line | |
|---|---|---|
| Type | Text string | |
| Value | A defined COM port on a host system in the form of "\\.\COMn" (or "COM<n>:") Example:
|
...
| Parameter | baud | |
|---|---|---|
| Type | Numeric | |
| Value | 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:

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: "Ctrl-P", "Break" or "none" ("none" disables triggering a HALT condition).
Example:
The default value is "Break".
|
...
| 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 Virtual Machine (VM) to exit. Specify the one of the following values: “F6” or “none” ("none" disables triggering a STOP condition). Example:
The default value is "none". Setting "F6" triggers the STOP condition upon receipt of the "

...
| 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 VM 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 VM does not create a console log. Examples:
|
...
| 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.
Examples:
|
...
| Parameter | application | ||
|---|---|---|---|
| Type | Text string | ||
| Value | 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:
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:

...
| 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: "Ctrl-P", "Break" or "none" to disable triggering a HALT condition. The commands are case insensitive.
Example:
The default value is "Break".
|
...
| 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 VM to exit. Specify one of the following values: “F6” or “none” ("none" disables triggering a STOP condition). The commands are case insensitive. Example:
The default value is "none". Setting "F6" triggers the STOP condition upon receipt of the "

| 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 VM 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 VM does not create any console log. Examples:
