18 Local

EnableLocal

Local - used in System Controller mode, issued to an
interface device; causes Driver488 to unassert the Remote
Enable (REN) line. This causes devices on the bus to return
to manual operation. A Local command addressed to an
external device, places the device in the local mode via the
Go To Local (GTL) bus command.

LocalList

EnableLocal

Like Local, but with list of devices.

19 Lol

SendLLO

SetRWLS

Lol - causes Driver488 to issue an IEEE 488 LocalLockout
(LLO). Bus devices that support this command are thereby
inhibited from being controlled manually from their
front panels.

20 MakeDevice

NO EQUIVALENT

MakeDevice - creates a new temporary Driver488 device
that is an identical copy of an already existing Driver488
external device. The new device is attached to the same I/O
adapter of the existing device and has the same bus
address, terminators, timeouts, and other characteristics.
The newly created device is temporary and is removed
when Driver488 is closed. KeepDevice may be used to
make the device permanent. To change the default values
assigned to the device, it is necessary to call the appropriate
configuration functions such as BusAddress, IOAddress,
and TimeOut.

MakeNewDevice

NO EQUIVALENT

MakeNewDevice - similar to MakeDevice, except new
device is based on the parameters specified, instead of
copying an existing device.

21 MyListenAddr

Also see:

Listen

EnableRemote

MyListenAddr - addresses the interface to Listen.

22 MyTalkAddr

NO EQUIVALENT

The MyTalkAddr command addresses the interface to Talk.

23 OnDigEvent;

OnDigEventVDM

NO EQUIVALENT

Digital commands. No equivalent MCC API commands.

OnEvent

NO EQUIVALENT

OnEvent - causes a message upon occurrence of an Armed
event. The message will have a type of:
WM_IEEE488EVENT

OnEventVDM

NO EQUIVALENT

OnEventVDM - allows a call back to a user-specified function
in an application.
