Lol
SYNTAX int pascal Lol(DevHandleT devHandle);
devHandle refers to either an IEEE 488 interface or an external device. If
devHandle refers to an external device, the Lol command acts on the
hardware interface to which the external device is attached.
RETURNS -1 if error
MODE CA
BUS STATES ATN
•LLO
SEE ALSO Local, LocalList, Remote, RemoteList
EXAMPLES errorcode = Lol(ieee);
The Lol command causes Driver488 to issue an IEEE 488 LocalLockout ( LLO ) bus command. Bus
devices that support this command are thereby inhibited from being controlled manually from their
front panels.
MakeDevice
SYNTAX int pascal MakeDevice(DevHandleT devHandle, char *name);
devHandle refers to an existing external device.
name is the device name of the device that is to be made and takes the
configuration of the device given by devHandle.
RETURNS Device handle, or -1 if error
MODE Any
BUS STATE None
SEE ALSO KeepDevice, RemoveDevice, OpenName, Close
EXAMPLE dmm=MakeDevice(scope,"DMM");
BusAddress(dmm,16,-1); Create a device named DMM, attached to
the same I/O adapter as SCOPE and
set its IEEE 488 bus address to 16.
The MakeDevice command 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
Driver488/W95 only
SYNTAX DevHandleT pascal MakeNewDevice(LPSTR iName, LPSTR aName,BYTE
primary,BYTE secondary,TermPT In,TermPT Out,DWORD tOut);
devHandle refers to the new external device.
Name is the device name of the device that is to be made and takes the
configuration of the device based on the parameters specified.
primary and secondary are the secondary and primary bus addresses to be
specified. For no secondary address, a -1 must be specified.
In and Out are pointers to terminator structures specified to set up the respective
input and output terminators of the device.
tOut is the timeout parameter to be specified.
RETURNS Device handle, or -1 if error
MODE Any
BUS STATE None
