Parameterline
TypeText string
Value
A defined TTY port on host system:
  • "/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
Warning

If a virtual console "/dev/tty<N>" is going to be used, it must be freed from all the processes running on it at first. Refer to your OS documentation for details, also some description on how to do it is available here.


Warning

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

Parameterapplication
TypeText string
Value

A command line for calling some host application for communication to Charon on a given serial line.

Example:

set OPA0 application = "xterm -title OPA0 -e telnet 127.0.0.1 10003"

If "putty" terminal emulator is going to be used as an option, copy the following file to your home directory:

# cp /opt/charon/putty/sessions/CHTERM-VT100 $HOME/.config/putty/sessions

Example:

set OPA0 application = "putty -load CHTERM-VT100 -title OPA0@XYZ -P10003"

connection_override

Parameter

connection_override

Typetext string
Value
"enable"
Allows new connection to override existing connection, if any. Enabled connection override on OPA0 allows to intercept virtual serial console.
When emulator detects new connection request on the port (10003 for the below example), it closes old connection, if any, and switches to the new one.
Example:
set COM1 alias = OPA0
set OPA0 port = 10003 connection_override = enable
(warning) This is implemented only for serial lines using the "set XXX alias=YYY"  syntax. Legacy lines are not supported.
