Console

CHARON-VAX offers a one- or four-port serial console depending on the specified VAX model. The one line serial line controller is identified in CHARON-VAX with the name UART. The four serial lines controller is identified in CHARON-VAX with the name QUART. 

...

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

A 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.


...

This command connects the first serial line ("line[0]") of a "QUART" serial line controller to a CHARON-VAX connection instance named "TTA0". As explained earlier, TTA0 may be a virtual serial line connected to port, or a physical serial line connected to host serial port or virtual terminal. In an 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/TTY port:

set TXA line[5]=TTA1

OPA0 console configuration examples

Using legacy syntax (not recommended)

This example, using a MicroVAX 4000-106, maps OPA0 to port 10003, enable F6 key (emulator stop) and logs the console input/output to a rotating log file in /charon/myvax/logs folder:

load virtual_serial_line OPA0

set OPA0 port=10003

set quart line[3]=OPA0

set OPA0 stop_on="F6"

set OPA0 log="/charon/myvax/logs"

Using new syntax (recommended)

This example, using a MicroVAX 4000-106, maps OPA0 to port 10003, enable F6 key (emulator stop), logs the console input/output to a rotating log file in /charon/myvax/logs folder and enables the connection_override feature:

set QUART alias[3]=OPA0  (optional starting with build 204-13)

set OPA0 port=10003

set OPA0 stop_on="F6"

set OPA0 log="/charon/myvax/logs"

set OPA0 connection_override=enable
