Drop the previous message. I found the nullpointer exception, but
still have trouble:
I run the example with the command:
/usr/lib/jvm/java-6-openjdk/bin/java -Djava.library.path=. -
cp .:smslib-3.4.5.jar:RXTXcomm.jar:slf4j-api-1.5.10.jar:slf4j-
log4j12-1.5.10.jar:log4j-1.2.15.jar misc/ReadMessages
Service object is made and instratiated: = OK!
Gateways are added = OK!
but when I reach the line:
System.out.println(" Manufacturer: " + gateway.getManufacturer());
it stops and times out, and I get:
xperimental: JNI_OnLoad called.

Now, You told me to insert the line:
<ServiceObject>.getSettings().SERIAL_RTSCTS_OUT = false.
BUT! That should is not effecting the serviceObject as it is only a
return value.
Would the correct way not be:
Settings tempSettings = srv.getSettings();
tempSettings.SERIAL_RTSCTS_OUT = false;
srv.setSettings(tempSettings);
... but unfortunately the setSettings(Settings) is for some reason a
private function and can not be accessed.
Any other ideas? I am pretty sure the RTSCTS is the problem!
