Some months ago, I was creating a Windows-based controller to manage a modem bank using Java. After initially trying serial drivers from RxTxComm, IBM and Sun each with various problems in stability and operational behavior, I purchased serialio.com's SerialPort package. I was immensely pleased when the package went in seamlessly with no coding changes (using the javax.comm.SerialPort layer), and more so that it has been working reliably ever since. The original goal was to control up to 16 modems on a mid-level (circa 2003) system, thanks in part to SerialPort's…

I found the SerialIO.com site via the Apple Developer Connection.  I knew it had to be a good outfit if Apple was willing to suggest them as a source.   I purchased the SerialIO SerialPort Java package and it worked right out of the 'box'.  Then, a month later, I ran into a problem which coincided with my purchase/use of a MacPro after my G5 konked out.  Sadly, things did not work on this Intel-based machine.  I was concerned about OS/Java hassles - and wrote to SerialIO support.   Shortly thereafter I got eMail support which helped me isolate…

SerialPort has saved me tons of time over the years. Your interface is very concise, straightforward, easy to use and very easy to deploy. SerialPort has been used in-house to deploy data acquisition for a custom wireless network implemented with UHF radio. In addition, we use it in-house for our transponder programming. Deployed at run-time, SerialPort is remarkably fast. I never have to worry if the serial code will keep up with the rest of the app. In fact, most of the time it's the other way around!

I would just like to say that your product SMOKES! The speed increase over the Sun implementation is amazing. Thanks again for the quick response.

Kudos to your development team for the ease of use of the Serialio product. The sample applications supplied with the software have been more than sufficient in aiding the development of our serial-based application designed for laboratory use. We were sending bytes to the port and receiving responses within a matter of minutes upon purchasing and downloading your serialio classes. The nominal product fee paid for itself in the first day.

We use the BlueSnap-XP is used to communicate remotely with a motor controller that interfaces with a submersible pumping system in an oil well. The system allows the operator to receive downhole sensor readings, start and stop the motor, and change settings on the motor controller; including frequency, alarm settings, and shutdown criteria; all from inside a trailer roughly 40 feet away from the surface equipment for the well.

I could not believe how easy it was to get the BlueSnap-AAA RS-232 serial Bluetooth Dongle to connect to and work with our Bluetooth enabled Sokkia Total Stations Surveying Equipment and HP50g calculator. Fully functional in 30 minutes out of the box (I budgeted 30-40 hours based on past experience with other technology products). It is absolutely fantastic!

I use the BlueSnap AAA Bluetooth Dongle to configure & troubleshoot Cisco equipment within large local deployments. Because of the short Cisco Console-Cable, I’m often limited where I have to stand and there is not always power when my notebook battery is empty. The battery operated BlueSnap AAA Bluetooth RS-232 dongle gives me the possibility to work from one place where it’s convenient and just move the dongle from one system to another.

Our company develops and markets technology for the knowledge of water (hydric resources) we purchased the BlueSnap Standard Bluetooth Dongles from SerialIO.com to be directly integrated onto the board of our equipment, which connects to an iPAQ 110 PDA that is used to take real-time data. Once installed, the devices have worked well without any issues.

I purchased a BlueSnapXP Bluetooth Dongle with a 4" Long-Range Antenna last fall. My experience with your product has been great, I used it to retrofit a very expensive GPS Correction unit so I'm able to eliminate many feet of cables. I have had no problems with the BlueSnap, the range and battery life of the product have been great. Thank you for providing a product as advertised.
