flushinput
(To be removed) Remove data from input buffer
This serial, Bluetooth, tcpip,
udp, visa, and gpib object
function will be removed in a future release. Use serialport, bluetooth,
tcpclient,
tcpserver,
udpport,
and visadev
object functions instead. For more information on updating your code, see Version History.
Syntax
flushinput(obj)
Arguments
| An interface object or an array of interface objects. |
Description
flushinput(obj) removes data from the
input buffer associated with obj.
Tips
After the input buffer is flushed, the BytesAvailable
property is automatically configured to 0.
If flushinput is called during an asynchronous (nonblocking)
read operation, the data currently stored in the input buffer is flushed and the
read operation continues. You can read data asynchronously from the instrument using
the readasync function.
The input buffer is automatically flushed when you connect an object to the
instrument with the fopen function.
You can clear the output buffer with the flushoutput function. You can
clear the hardware buffer for GPIB and VXI instruments with the clrdevice function.
