While I am glad to see that the aux-handler can be patched, I am a little shocked that you see AUX: as having limited usefulness. Indeed, for some folks, it is far more useful than SER:, allowing as it does, an easy way to use a shell or an application normally run using stdin/stdout over a serial port. Does your ZapPort utility patch executables in a generic manner? The reason I ask is that the aux-handler I use is not the one supplied by CBM, but has been improved significantly. -larry -- "Cavett Emptor - Let the talk show host beware!" - Evan Marcus +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
