Can anyone tell me either how(or where) I can find info on using the ports on a PC(you know, the kind you put your printer on) thru a APPLET. If you give me a great response, I'll quadruple the points.

TIA, Matt Lesko

You have to use native methods (an api to interface with machine specific functions) or use a daemon to transfer everything from the machine the applet was launched from.

It should be noted that, naturally, any use of native methods is not multiplatform. Nor will it be generally loadable across the Net. I mention this, since you specified APPLET in capitals.

There is a communications API forthcoming that will handle this to some extent or other. See http://developer.javasoft.com.

Here is a site where you can find a serial port control for Java. It works on most of the platforms. There is a free trial version, but you should buy it (it's not expensive):

But don't forget that there are security limitations when using applets over the Net. Local applets have no restrictions of course.
