Description
The OPA0 object configures the virtual serial console, it is always present and therefore does not have a load statement.
The type member of the OPA0 object indicates what kind of serial console the virtual Alpha is to use. The following table describes the supported values.
| Type | Description |
|---|---|
| device | Connect the virtual console to a physical serial device attached to the host system (i.e. COM1). |
| socket | Attach the virtual serial console to a raw TCP/IP listener socket on the host. |
| telnet | Attach the virtual serial console to a TCP/IP listener socket on the host |
The value of the port member depends on the setting of the type member. For the socket and telnet types, port can be set to an unused TCP/IP port number. This port-number must be prefixed with a colon. For the port type of device, the value must be a serial device physically available on the host and the name must be suffixed with a colon.
The command member can be used to start a terminal emulator as part of the virtual machine start up.
The stop_process member is used to kill the console terminal emulator started by command when the virtual machine powers off. It has a default value of "yes". However, sometimes it is important to retain the console output, even after power off in which case stop_process would be set to "no".
The OPA0 object is not supported under CHARON-AXP/Station.
