Closed GoogleCodeExporter closed 9 years ago

Hi,

Currently I'm working on SMS gateway kind of application.
In receiving AT-Command result from port, there are many pattern to capture 
before I start to be able to process the incoming SMS.
Is there any way, I can detect when the port has finished sending byte[]?.

Thanks
Bromo

For that you can use SerialPortEventListener and SerialPort.MASK_TXEMPTY event 
for checking state of output buffer. Not all serial port devices support this 
event, and the second way is to use getOutputBufferBytesCount() method of 
SerialPort class, you can run a standalone thread for checking this parameter, 
this method return a count of bytes in output buffer and if this value == 0, 
it's mean that your output buffer is empty and serial port don't send any data.
