MODE CA
BUS STATES ATN
•PPU
SEE ALSO PPoll, PPollConfig, PPollDisable
EXAMPLE errorcode = PPollUnconfig(ieee);
The PPollUnconfig command disables the Parallel Poll response of all bus devices.
Remote
SYNTAX int pascal Remote(DevHandleT devHandle);
devHandle refers to either an interface or an external device. If devHandle
refers to an interface, then the Remote Enable ( REN ) line is asserted. If
devHandle refers to an external device, then that device is addressed to
Listen and placed into the Remote state.
RETURNS -1 if error
MODE SC
BUS STATES REN (hardware interface)
REN, ATN
•UNL, MTA, LAG (external device)
SEE ALSO Local, LocalList, RemoteList
EXAMPLES errorcode = Remote(ieee); Assert the REN bus line.
errorcode = Remote(scope); Assert the REN bus line and address the
SCOPE device specified to Listen, to
place it in the Remote state:
The Remote command asserts the Remote Enable ( REN ) bus management line. If an external device is
specified, then Remote will also address that device to Listen, placing it in the Remote state.
RemoteList
SYNTAX int pascal RemoteList(DevHandlePT devHandles);
devHandles is a pointer to a list of devices.
RETURNS -1 if error
MODE SC
•CA
BUS STATES REN, ATN
•UNL, MTA, LAG
SEE ALSO Remote, Local, LocalList
EXAMPLE deviceList[0] = wave;
deviceList[1] = timer;
deviceList[2] = dmm;
deviceList[3] = NODEVICE;
errorcode = RemoteList(deviceList); Assert the REN bus line and
address a list of specified
devices to Listen, to place
these specified devices in
the Remote state.
The RemoteList command asserts the Remote Enable ( REN ) bus management line. If external
devices are specified, then RemoteList will also address those devices to Listen, placing them in the
Remote state.
RemoveDevice
SYNTAX int pascal RemoveDevice(DevHandleT devHandle);
devHandle specifies an interface or an external device to remove.
RETURNS -1 if error
MODE Any
BUS STATES None
SEE ALSO MakeDevice, KeepDevice, REMOVE DOS NAME (Sub-Chapter 15A)
EXAMPLE errorcode = RemoveDevice(dmm);
