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? Posted in Java at Jun 03 2003, 11:43:30 PM MDT 2 Comments

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

Why not have a look at the Ethereal source code?
