Reading Ports and Frames in Java My dad has an issue that maybe y'all can help with. He needs a class or library that can read from ports, addresses, and a "frame" (including the header). I asked him what he meant my all this, and here's what he wrote back.
In Pascal it would be a Procedure that reads a location. The location being an address or a hardware port like an RS-232 port, as opposed to a socket or Port 80 for HTML.
Ethernet transfers data in Packets or Frames and you can limit the size of the frame (fragment for optimal efficency); although, Ethernet (802.3) including 802.11x have a maximum size packet (Frame). The nomenclature changes according to the OSI Model Layer you're reading from.
Any ideas?

If it's memory addresses, wouldn't that fall under the auspices of JNI?
As far as serial/parallel ports go, maybe try Java Cookbook Chapter 11
