My java application communicates with datalogger via rs232. Rxtx library works fine on *linux and windows system using serial port. The problems come when I use an usb* adapter* FTDI chip-set based (http://www.ftdichip.com/Products/Eva.../US232R-10.htm) on my lunux system (2.6.24 kernel), where there is no need of driver. On windows instead I have no problem. My program is event based; This adapter works correctly using Mincom. But in my program I use serialPort.notifyOnDataAvailable(true) and serialPort.notifyOnOutputEmpty(true)* calls.
My application send first message correctly but I get an error in response:
at gnu.io.RXTXPort.sendEvent(RXTXPort.java:732)
at gnu.io.RXTXPort.nativeDrain(Native Method)
at gnu.io.RXTXPort$SerialOutputStream.flush(RXTXPort.java:1201)

*If I comment flush() command after send first message I have no response and my time-out exceeds. It seems there are problems when generating SerialPortEvent.DATA_AVAILABLE event.
How can I resolve this problems ?

hi!
i encounter exact same same problems as you do. my SerialPortEventListener never receives any SerialPortEvents.
have you already found any solution to this? i really would appreciate any help!
thx so far,
tobias

I develop a "polling" logic.


/** */
public class SerialWriter implements Runnable
{ //TRAnSMISsion
OutputStream out;

public SerialWriter ( OutputStream out )
{
this.out = out;
}

public void run ()
{
try {
while(end==false){......






public class SerialReader implements Runnable
{ //RICEIVING
InputStream in;
MisureUtil misureUtil = new MisureUtil();

public SerialReader ( InputStream in )
{
this.in = in;
}

public void run ()
{
try {
while(end==false){...

I use semaphore variable.
Bye.
