Use the following command to load an instance of an LPV11 Parallel Line Printer Controller:
load CHAPI <logical name> dll=LPV11 |
Example:
load CHAPI LPA0 dll=LPV11 |
The LPV11 (being a CHAPI component) provides the following configuration parameters, to be specified using the "set" command:
address
| Parameter | address |
|---|---|
| Type | Numeric |
| Value | Specifies the CSR address. This address must be a valid QBUS 22-bit address in an I/O space. The initial value is 017777514, which is the factory setting for an LPV11. |
vector
| Parameter | vector |
|---|---|
| Type | Numeric |
| Value | Specifies the interrupt vector. The initial value is 0200, which is the factory setting for an LPV11. |
parameters
| Parameter | parameters | ||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Type | Text String | ||||||||||||||
| Value | Specifies the name of the file in which the LPV11 prints the text, the name of a physical printer or a TCPIP port to connect to an external utility, like HOSTPrint, (along with some additional parameters):

It’s possible to load as many LPV11 devices as you wish and the system running on the emulated VAX/PDP-11 allows this to be done. To load LPV11 devices use the standard QBUS parameters: "address" and "vector" to select the correct place on the QBUS.
The following example demonstrates how to load 2 instances of LPV11, mapped to 2 host system LPT ports:

| Note |
|---|
The printers connected to the host must understand output of the LPV11 driver on the emulated VAX/PDP-11. Use printers that work with the VAX/PDP-11 hardware. |
...
In the following example the LPV11 instance, called: lpv1, opens host port 10004 and starts the HOSTPrint application, directing it to connect to the port 10004 and use the font "Courier New", size 12 for printing:

DUMMY_VCB02 device
| Info |
|---|
This description applies only to MicroVAX 3600, MicroVAX 3900, VAXserver 3900 and VAXserver 3600 server emulations. |
...
The format is as follows:
load dummy_vcb02/null_vcb02 dummy |
| Note |
|---|
Since this dummy device cannot draw graphics, CHARON-VAX will fail the initial hardware diagnostics, but it will still boot correctly. |
