 There are few pieces in your simple explanation that I don't understand:
- How does listener get a device name?

There may be multiple ways, but if using the SYS$QIO(W)
interface then the code has a channel and SYS$GETDVI(W)
can get the device name from that.

- What is "channel"? Is it the same as 'socket'?

I assume a VMS channel as one get from SYS$ASSIGN.

- How one "assigns" channel to device? I would guess that device has to
be open before that?

Call SYS$ASSIGN.

- Is device name of the socket system-global?
If yes, does it mean that any process in the system that happens to
know a name can open a device and assign it to channel?

Device names are system wide.
But there are access controls in place.
