General Description
CHARON-AXP offers two-port serial console on all supported AXP models.
Example for OPA0 console ("COM1" port):
|
When using the TTA0 console ("COM2" port):
|
Refer to Mapping Serial line controllers to system resources for details of mapping.
General parameters
CHARON-AXP console lines COM1 and COM2 have the following parameters:
All the values in the following tables are case insensitive.
alias
Parameter | alias | |
|---|---|---|
Type | Identifier | |
Value | This parameter is used to set an useful name for COM1 or COM2 ports. It can be any name, for example "Console1", but usually it is "OPA0" for COM1 and "TTA0" for COM2. This name is logged in CHARON log file, it can also be used for parametrization in CHARON configuration file along with "COM1" and "COM2" identifiers. The main purpose of this parameter is migration from old CHARON systems (which do not have the described implementation of consoles) to the current design, since it allows retaining the original name used for parametrization, since the rest of the parameters stay the same in both implementations. If the "alias" parameter is not specified CHARON log file will miss the name for the given console, for example " : Connected. Remote 127.0.0.1:63516" will be displayed instead of "OPA0 : Connected. Remote 127.0.0.1:63516". So it is always recommended to specify the "alias" parameter. Example:
|
communication
Parameter | communication |
|---|---|
Type | Text string |
Value |
|
baud
Parameter | baud | |
|---|---|---|
Type | Numeric | |
Value | Forces the baud rate of the corresponding TTY port to a specified value.The variety of supported values depends on the underlying physical communication resource (TTY 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. Specify the following values: "Ctrl-P" , "Break" or "none" ("none" disables triggering a HALT condition). If your guest operating system is OpenVMS in addition to "none" setting you have to set a specific console parameter "controlp" to "off" in the following way: The second line is to preserve the ROM settings. Example:
The default value is "Break". This parameter can be specified only for COM1 (OPA0) console |
