Truth be told, you could just print "Hit ESC now to continue" and disconnect if the ESC key (or whatever key you like) isn't hit within a few seconds. No bot is going to hit the ESC key - problem solved. You don't really *need* to display/prompt for a random anything since nobody is going to build a BBS-specific bot (they just aren't a target of interest).ããIf you're running a recent build of Synchronet with a recent login.js, it'll disconnect dumb terminals (those not supporting ANSI or any other emulation) very quickly when no input is sent and that disconnect time is configurable.ã-- ã digital manããRush quote #57:ãHe picks up scraps of information, he's adept at adaptation ..
