OutputI Function Terminators Variable
OutputXI(ADC,IResp (0),1000,1,Term,1,1) Choice Pass starting location
OutputI (ADC, IRESP())
OutputMoreI (ADC, IResp ()) Yes Pass entire array
OutputNI (ADC< IResp (0), 1000)
OutputNMoreI (ADC, IResp (0), 1000) No Pass starting location
where: SResp is String * 1000 , and IResp(1000) is integer .

OutputXI
SYNTAX OutputXI (ByVal devHandle%, data%, ByVal count&, ByVal last%,
ByVal forceAddr%, Term As terms, ByVal async%, compstat%)
As Long
devHandle% refers to either an interface or an external device.
data% points to the bytes to send.
count& is the number of characters to send.
last% is a flag that forces the device output terminator to be sent with the data.
forceAddr% is ignored.
terms is a pointer to a terminator structure that is used to set up the output
terminators. If terms is set to 0 , the default terminator is used.
async% is a flag that allows asynchronous data transfer.
compStat% is a pointer to an integer containing completion status information.
RETURNS -1 if error; otherwise, the number of characters transferred
MODE *CA
BUS STATES Determined by the Controller.
SEE ALSO EnterI, Term, TimeOut, Buffered
The OutputI commands for Visual Basic are identical to the standard Output commands except that
they use an integer array for the output data rather than a string.
In Peripheral mode, the OutputXI command sends data to the interface under control of the Active
Controller. The Active Controller must put the interface into the Talk state and configure some bus
device to accept the transferred data. The Talk state can be checked with the
Status command, or can
cause an interrupt via the Arm command. A time-out error occurs, if enabled, if no bus device accepts
the data within the time out period after issuing the OutputXI command. Even as a Peripheral,
Driver488 might be the System Controller. If Driver488 is the System Controller and AutoRemote is
enabled, then Driver488 asserts Remote Enable ( REN ) before sending any data. The OutputXI
command in Peripheral mode is otherwise identical to the OutputXI command in Controller mode.
Additional OutputI Functions
Driver488 provides additional OutputI functions that are short form versions of the OutputXI
function. The additional OutputI functions are: OutputI and OutputNI . In Peripheral mode, the
device handle must always refer to an I/O adapter, and the forceAddr% flag is ignored. Thus,
OutputMoreI is equivalent to OutputI , and OutputNMoreI is equivalent to OutputNI .
