Well, actually 3184 bytes. Some of you may know about the packet drivers I've been working on. They do two things: hide the difference between ethernet cards behind a software interface, and allow multiple protocols to access the same ethernet card. Well, I've written a little TSR that implements ARP, IP, and UDP in slightly more than 3K bytes. It gloms onto the packet driver interface, and gets out of the way when a real TCP/IP package tries to use the packet driver. It implements a UDP protocol that accepts a message directed to a given user at a given terminal. Of course, this PC implementation ignores both of the latter parameters. The message is displayed on the 25th line of the screen for five seconds, or until you press a key. I wrote it because I wanted to be informed of mail received on our Unix host. Anyway, the official port number hasn't been assigned yet, and the program needs a little polishing, but I couldn't resist bragging about my latest hack. I *will* publish this soonest. -- --russ (nelson@clutx [.bitnet | .clarkson.edu]) Russ.Nelson@$315.268.6667 Violence never solves problems, it just changes them into more subtle problems
