General Description

CHARON-AXP offers a one- (OPA0) or two-port serial console, depending on the specified HP Alpha model.

The AlphaServer DS10, AlphaServer DS10L, AlphaServer DS15, AlphaServer 400, AlphaServer 800, AlphaServer 1000 and AlphaServer 1000A has an additional on-board serial line controller providing a serial line TTA0.

The regular console is already preloaded, so you need to specify just its mapping to the host resources, for example:

load physical_serial_line OPA0 line="COM1:"

In case of the TTA0 console the mapping looks like that:

load virtual_serial_line TTA0 port=10000
set COM2 line=TTA0

The first line specifies a mapping to a unique TCP/IP host port ("10000" in this example), while the second line connects this mapping (TTA0) to the on-board serial line controller having the name "COM2" in CHARON environment.

Refer to this section for details of mapping.

CHARON emulated console supports only 80 symbols in one line.

Console Parameters

CHARON-AXP console line TTA0 (COM2) has the following parameters:

All the values in the following tables are case insensitive

communication

Parameter	communication
Type	Text string
Value	"ascii" - for connection to terminals (default) "binary" - for binary (packet) protocols, which are used mainly for communicating with PLCs

line

Parameter

line

Type

Identifier

Value

This parameter is used to connect a particular serial line mapping interface to the controller.

Example:

set COM2 line=TTA0

Example

set COM2 communication="binary"

Mapping Serial line controllers to system resources

Types of serial line mapping:

Type	Function

Type

Function

physical_serial_line

This type of mapping associates a COM port on a host system with an emulated HP Alpha serial line controller virtual "line".

The COM port can be a physical hardware port or a logical COM port.

virtual_serial_line

This type of mapping associates a network connection on the host system with an emulated HP Alpha serial line controller virtual "line"

Example:

load physical_serial_line TTA0
