...
load PBXDA/DIGI <name>
Syntax for loading PBXDA_BA (AccelePort 4r 920) serial lines adapter:
...
load PBXDA_BA/DIGI <name>
Syntax for loading PBXDA_BB (AccelePort 8r 920) serial lines adapter:
...
load PBXDA_BB/DIGI <name>
Syntax for loading PBXDA_AC (AccelePort Xem) serial lines adapter:
...
load PBXDA_AC/DIGI <name>
Example:
...
The adapter instance name ("TXA" in the example above) is used then for parametrization, for example:
...
The numbers in the square brackets represent line number on the virtual PBXDA adapter starting from 0.
...

A defined TTY port on host system:
| Syntax | Description |
|---|---|
| "/dev/tty<N>" | Virtual serial lines |
| "/dev/ttyS<N>" | Onboard serial lines |
| "/dev/ttyUSB<N>" | Modem or USB serial lines adapters |
| "/dev/tty<XXX>" | Proprietary (depending on a driver) devices such as DIGI or MOXA cards |
Example:
set TXA line[2]="/dev/ttyS1"
| Note |
|---|
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:
...
"/dev/tty<N>"
where N is from 0 to 11
...
Those tty devices must be free from the Linux "getty/mgetty" and similar programs (specified in "/etc/inittab")
Example:
"/dev/tty1" |
...
"/dev/ttyS<N>"
where N is a number
...
Example:
"/dev/ttyS1" |
...
"/dev/tty<XXX>"
where XXX is a complex letter/number notation
...
Example for a first port of a MOXA card:
"/dev/ttyR01" |
Example for a first port of a DIGI card:
"/dev/ttyaa" |
...
"/dev/ttyUSB<N>"
where N is a number
...
Example:
"/dev/ttyUSB1" |
...
- No extra parameters need to be set/changed.
- Once the controller is loaded it uses the host default audio card for audio playback via "PulseAudio" package.
- On OpenVMS side one must have MultiMedia services for OpenVMS package (MMOV) installed (available with OpenVMS CDL) along with MMOV-RT license.
