General description
CHARON-AXP supports emulation of PBXDA-xx family PCI serial adapter based on DIGI AccelePort serial adapters via CHARON PCI Pass Through mode (using a specific CHARON PCI Pass Through driver) and by direct virtualization.
CHARON PCI Pass Through mode enables connection between the virtual PBXDA-xx PCI serial adapter and the physical DIGI AccelePort PCI serial adapter plugged into a hosting server PCI bus whether as the direct virtualization may address the host serial port or TCP/IP port.
Virtual PBXDA-xx PCI serial adapter
Loading virtual PBXDA-xx serial lines adapter
Syntax for loading PBXDA (AccelePort 2r 920) serial lines adapter:
...
The numbers in the square brackets represent line number on the virtual PBXDA-xx adapter starting from 0.
| Controller type | Maximum number of lines |
|---|
| PBXDA | 2 |
| PBXDA_BA | 4 |
| PBXDA_BB | 8 |
| PBXDA_AC | 16 |
...
...
| Note |
|---|
DIGI drivers for OpenVMS and Tru64 are sensitive to PBXDA-xx location on PCI, therefore it is recommended to fix PBXDA-xx location with explicit configuration. For exampleExample:

Configuration parameters
The PBXDA-xx serial lines adapter emulation has the following configuration parameters:
port
| Parameter | port |
|---|
| Type | Text String |
|---|
| Value | Specifies a local port for incoming telnet connections By default the "port" configuration option is not specified. Syntax: port[line-number]=<local port> |
Example:
|
|---|
line
| Parameter | line |
|---|
| Type | Text string |
|---|
| Value | A defined COM port on host system: Example: set TXA line[2]="COM2:"

Configuration parameters
The PBXDA-xx PCI serial adapter emulation has only one configuration parameter:
host_bus_location
| Parameter | host_bus_location |
|---|
| Type | Text String |
|---|
| Value | Establish connection between virtual PBXDA-xx PCI serial adapter and physical DIGI AccelePort PCI serial adapter installed on CHARON host (pass through mode) Syntax: load digi <controller name> host_bus_location="PCI bus X, device Y, function Z" |
where: | Parameter | Description |
|---|
| "PCI bus X" | PCI bus number of the host DIGI AccelePort PCI serial adapter | | "device Y" | PCI bus device number of the host DIGI AccelePort PCI serial adapter | | "function Z" | The "function" parameter of the the host DIGI AccelePort PCI serial adapter |
Example: load digi SERIAL_A host_bus_location="PCI bus 3, device 1, function 0" |

Installation of DIGI AccelePort PCI serial adapter
- Install the DIGI AccelePort PCI serial adapter to some spare PCI slot of the host system
- Boot a Windows operating system
- Open “Computer Management”
- Select “Device Manager”
- In the right window select the desired physical serial adapter connected to the system, right-click the mouse button, and the corresponding menu will appear.
- From the menu select “Update driver…”. Windows will show “Hardware Upgrade Wizard”
- Select “No, not this time”, click “Next”
- Select “Install from a list or specific location (Advanced)”, click “Next”
- Select “Don’t search. I will choose the driver to install”, click “Next”
- Click “Have Disk…”. Windows shows dialog “Install From Disk”
- Instead of “A:\”, click “Browse” and select path to the folder in which driver’s INF file is located (typically "C:\Program Files\CHARON\Drivers\DIGI_X.X.0.XXXXX"), select “digi_ppt_amd64.inf”, and click “Open”
- The “Hardware Upgrade Wizard” should have “CHARON DIGI adapter”. Select it, and click “Next”
- There will be one or two more dialogs, but they are usual for device driver installation.
- Reboot the host
