(To be removed) Send break to device connected to serial port
This serial object function will be removed in a future release. Use
serialport
object functions instead. See Compatibility Considerations.
serialbreak(obj)
serialbreak(obj,time)
serialbreak(obj) sends a break of 10
milliseconds to the device connected to the serial port object,
obj.
serialbreak(obj,time) sends a break to the
device with a duration, in milliseconds, specified by time. Note that
the duration of the break might be inaccurate under some operating systems.
For some devices, the break signal provides a way to clear the hardware buffer.
Before you can send a break to the device, it must be connected to
obj with the fopen function. A connected
serial port object has a Status property value of
open. An error is returned if you attempt to send a break while
obj is not connected to the device.
serialbreak is a synchronous function, and blocks the command
line until execution is complete.
If you issue serialbreak while data is being asynchronously
written, an error is returned. In this case, you must call the
stopasync function or wait for the write operation to
complete.
