Loading the virtual serial lines' controller, for example:
load DHV11/DHV11 TXA
In this example, an instance of a "DHV11" serial line controller is loaded and named "TXA".
Note that the VAX/PDP11 console adapters ("UART", "QUART") do not need to be loaded; they are preloaded.
Mapping an object type to host resources. For example:
load virtual_serial_line/chserial TTA1
set TTA1 port = 10003 application = "putty.exe -load TTA1_preset"In this example the object "virtual_serial_line" is loaded, named "TTA1", mapped to the "putty" terminal emulator and connected to this CHARON instance using the port 10003 (this setting is encoded in the "TTA1_preset" parameter of the "Putty" terminal emulator).
Div class pagebreak Connect the loaded virtual line controller and the mapped object:
set TXA line[5]=TTA1
In this example, the 6th line of the DHV11 controller, "TXA", loaded in step 1, is connected to the mapping object, "TTA1", loaded in step 2.

CHARON-VAX / CHARON-PDP console ports can be configured to connect to an external terminal via the host system COM port or can be connected via TCP/IP.

Use the "address" and "vector" parameters to load several instances of the Qbus multiplexers. Both "address" and "vector" parameter values must be unique for every instance of a QBUS multiplexer.
Read the VAX/PDP11 hardware documentation and the VM system management documentation to understand how to correctly assign the "address" and "vector" parameters.

Types of serial line mapping
Type | Function |
---|---|
physical_serial_line | This type of mapping associates a COM port on a host system with an emulated VAX/PDP11 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 VAX/PDP11 serial line controller virtual "line" |
Example:
load physical_serial_line/chserial OPA0 |
...
physical_serial_line

line
Parameter | line | |
---|---|---|
Type | Description | |
line | Text string | |
Value | A defined COM port on a host system in the form of "\\.\COMn" Example:
|
baud
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 (for the one UART line and "line[3]" of QUART). Specify the following values: "CrtlCtrl-P", "Break" or "none" ("none" disables triggering a HALT condition). Example:
The default value is "Break" for line 3 of QUART and "none" for other lines. |
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-VAX / CHARON-PDP 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 " |
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-VAX / CHARON-PDP 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-VAX / CHARON-PDP does not create a console log. Examples:

host
Parameter | host | |
---|---|---|
Type | Description | |
host | 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:
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. |
application
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:
|
break_on
Parameter | break_on | |
---|---|---|
Type | Text string | |
Value | Specifies what byte sequences received over a virtual serial line triggers a HALT command. This parameter works only on the console line (for CHARON-VAX / CHARON-PDP it is the only line of UART and "line[3]" of QUART). Specify one of the following values: "CrtlCtrl-P", "Break" or "none" to disable triggering a HALT condition. The commands are case insensitive. Example:
The default value is "Break" for line 3 of QUART and "none" for other lines. |

Use the combination of "port" and "host" parameters as follows to connect a 3rd party terminal emulator or similar program.
load virtual_serial_line/chserial TTA0 host="192.168.1.1" port=10000
In this example CHARON-VAX / CHARON-PDP 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/chserial TTA0 host="192.168.1.1:20000" port=10000
Note: the examples above are mainly used for inter-CHARON communications. They are used to connect CHARON-VAX / CHARON-PDP to an application that communicates to CHARON-VAX / CHARON-PDP as described below.

Linking serial controller port to host connection
...
set <serial controller instance name> line[<line number>]=<serial line instance name> |
Example:
set quart line[0]=TTA0 |
This command connects the first serial line ("line[0]") of a "QUART" serial line controller to a CHARON-VAX / CHARON-PDP connection instance named "TTA0". As explained earlier, TTA0 may be a virtual serial line connected to a port or a physical serial line connected to a host serial port or a virtual terminal.
In the example below, the command connects the sixth serial line of a previously loaded controller (named "TXA") to "TTA1". "TTA1" could be defined, for example, as a physical serial line connected to COM/COM port:
set TXA line[5]=TTA1 |
