i believe you copy it to a str and compare it

just by checking if it's an exact number you can use that code i posted.
and that's what your capcha does, right

anyways, those bots will not solve your capcha. they will get confused and sit
on the connection.

Yup. 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).

If 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.
