Here's what I've been able to figure out about DesTerm overlays: Load address: $b000 Start address of code: $b005 End the routine with an RTS. Use the DesTerm "comp.ovl" file as a template for bytes $b000 - $b004. I'm not sure how much room you have to play with, but it is at least 10 pages. That's the size of "comp.ovl." ******************************************************************************* * Randy Winchester * randy@mit.edu * PO Box 1074, Cambridge, MA 02142 * *******************************************************************************

I have seen a fairly thick paperback book called something like _The Kermit File Transfer Protocol_. It is written by the original developers of Kermit, so is very detailed and explicit in its description. I don't recall the author's names, but I'm sure Caltech's libraries would have it.

Randy, Bill, thank you both for the info. Regarding DesTerm, does anybody know if there are system routies for things like disk access, RS-232 access, and perhaps keyboard/screen I/O which a potential overlay programmer could access? Thanks, -Rob rknop@tybalt.caltech.edu

Why not ask Matthew Desmond, since he IS on the net somewhere...I just can't find his E-mail address at the moment. However, I have seen him post to this forum many times. Oh wait, here it is...he lists his mail address as desterm@spinq or desterm@zswamp via UUCP. -- David DeSimone, aka "Fuzzy Fox" on some networks. /!/! INET: an207@cleveland.freenet.edu / ..
