I've been chatting with an ex-C= employee who was last working on bridgeboards. I was trying to convince someone that a Rexx port in the Janus software would be a tremendous idea, but everyone I talk to has some reason or other why it can't be done. This fellow seemed to be implying that PC screen isn't really software driven as we might believe, but hardware driven. Therefore, it would require some kind of gruesome hack running on the PC side to send data to a Rexx port. I personally can't understand this, as the clipboard recognizes the PC screen.
