Reading MAGTEK peripheral devices on JSP/J2EE platforms

[Jaywant Dharwadkar]

We are developing a Web application on J2EE platform and require to
support cetain peripheral devices such as MAGTEK PinPad and Card Swipe
(http://www.magtek.com/) connected to a PC port.

I am thinking of having two threads, one for reading from the port and
one to write to the port. The whole purpose of doing this is to
support the MAGTEK Pin Pad peripheral device on a Browser. The device
is connected to the COM5 port and it simulates the keyboard. So once
the data is keyed on the Pin Pad it is transfered to the port from
where the application would be reading it.

Following are my questions.
1. How are overlapped I/O operations supported in Java?
2. Are there any API's for doing the same?

Any comments or suggestions are appreciated.
