| 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:
|
Minimum log file size is 64K, maximum is 1G. Setting size less then 64K effectively makes the log file unlimited.host
| Parameter | host |
|---|---|
| Type | Text string |
A remote host’s IP address or hostname (and optionally a remote TCP/IP |
port
...
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. |
...
| Parameter | application |
|---|---|
| Type | Text string |
| Value | A command line for calling some host application for communication to CHAARON Charon on a given COM line. Typically this parameter is used for mapping COM1 or COM2 ro or some "xterm" terminal emulator Example:

Notes on "

port" and "application" parameters
...
Use the combination of "port
...
" and "application" parameters as follows to connect a 3rd party terminal emulator or similar program.
set COM1 alias=OPA0 port=10003 application="xterm -title OPA0 -e chterm -h 127.0.0.1:10003" |
In this example CHARON-AXP OPA0 console connects to port 10003 of localhost ("127.0.0.1") and at the same time it starts "xterm" with parameters "-title OPA0 -e chterm -h 127.0.0.1:10003", instructs it to connect to the port 10003 of the host with TCP/IP address "127.0.0.1" (localhost)
It is possible to specify a port on a remote host (note that CHARON always acts as a server). The syntax is:
set COM2 alias=TTA0 host="192.168.1.1:20000" port=10000In 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":

On host "B":
