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.

Syntax for loading PBXDA_BB (AccelePort 8r 920) serial lines adapter:
|
Syntax for loading PBXDA_AC (AccelePort Xem) serial lines adapter:

Example:
load PBXDA/DIGI TXA |
The adapter instance name ("TXA" in the example above) is used then for parametrization, for example:
set TXA line[2]="COM1:" |
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 |

All the parameters described in the "Placement of peripheral devices on PCI bus", such as "bus", "device", "function", "irq", "irq_bus" are applicable for PBXDA controller. |
| 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 example:

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
