General description
PBXDA is a PCI serial lines adapter based on the AccelePort 2R 920, 4R 920, 8R 920 and Xem DIGI adapters.
Loading PBXDA serial lines adapter
Syntax for loading PBXDA (AccelePort 2r 920) serial lines adapter:
|
Syntax for loading PBXDA_BA (AccelePort 4r 920) serial lines adapter:
|
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]="/dev/tty0" |
The numbers in the square brackets represent line number on the virtual PBXDA adapter starting from 0.
| Controller type | Maximum number of lines |
|---|---|
| PBXDA | 2 |
| PBXDA_BA | 4 |
| PBXDA_BB | 8 |
| PBXDA_AC | 16 |
DIGI drivers for OpenVMS and Tru64 are sensitive to PBXDA location on PCI, therefore it is recommended to fix PBXDA location with explcit configuration.
Example:
load PBXDA TXA bus=pci_1 device=4 function=0
Configuration parameters
The PBXDA 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:
Example:
|
line
| Parameter | line |
|---|---|
| Type | Text string |
| Value | A defined TTY port on host system:
Example:
If a virtual console "/dev/tty<N>" is going to be used, it must be freed from all the processes running on it at first. Refer to your OS documentation for details, also some description on how to do it is available here. A specific account for running CHARON ("charon") does not allow usage of physical consoles " |
"ttyY" notation specifics
Note that the "ttyY" notation can have different forms depending on the nature of the device used:
| Mapping | Type | Commentary |
|---|---|---|
"/dev/tty<N>" where N is from 0 to 11 | Linux virtual tty | Those tty devices must be free from the Linux "getty/mgetty" and similar programs (specified in "/etc/inittab") Example:
|
"/dev/ttyS<N>" where N is a number | Onboard serial lines | Example:
|
"/dev/tty<XXX>" where XXX is a complex letter/number notation | Proprietary (depending on a driver) devices | Example for a first port of a MOXA card:
Example for a first port of a DIGI card:
|
"/dev/ttyUSB<N>" where N is a number | Modem or USB serial lines adapters | Example:
