Lonely Cat Games Mau Mau Keygen Download on this page. Cannot find anything wrong with the code, but I can suggest some starting points for debugging: • Try the same code with Sun's (errr. Oracle's) javax.comm implementation.

The Windows version is no longer available for download from their site, but it can still be found in other places. Even if you don't want to use this implementation in your final setup, it might help you find the problem. There are also other alternatives such as. • Use to install a virtual com port.

Enable logging (see last question in the ). Compare the logs when you use your code with the logs you get when using HyperTerminal, and look for any differences. • Try a different serial ->USB converter. In my experience, many of these don't implement RS232 properly, or have plenty of bugs. Edit: If you discover that this is actually a rxtx bug, but for some reason don't want to switch to another javax.comm implementation (I've seen this happen:-) here are some additional hints that may be useful (I would try the above suggestions first anyway): • Are the calls to setInputBufferSize, setOutputBufferSize required? Try removing them. Does the device actually use XON/XOFF flow control?

Also, try to set the serial port params before opening the output stream. Of course, none of this should make any difference, but you might be triggering some rxtx bug. • Is the problem related to opening and closing the port in sequence several times? You could try to keep the port always open. On each sale, just do: outputStream.write('k'.getBytes()); outputStream.flush(); And see if the problem still reproduces.

I'm trying to write a java application that accesses the usb ports to read from and write to a device connected through usb. The problem I face is that I don't know what exactly to use in java to do such a thing.

I searched online and found something called JUSB but all the posts seem fairly old. Currently I'm using the RXTX libraries but I sometimes run into some sync error. Bei Anruf Bohlen Kostenlos Musik. When I use C# to do the equivalent it requires far less code and I don't face any of the same sync error.

My question is, is there anything built into the latest version of the JRE I can use to access the usb ports ( that is just as easy as the equivalent C# code)? There is nothing equivalent to C#'s USB support in Java. Both jUSB and Java-USB are severely out-of-date and likely unusable for any serious application development.
