Don't pass-through ANSI Device Attributes (DA) requests

putmsg(), used to display messages and display/menu files, will no longer pass-through the ANSI sequence ESC[c (found in some corrupted ANSI posts to fsxNet->FSX_BOT echo) to the client terminal since this will stimulate a (unwanted) response from the client.

I do wonder if the outchar_esc value check should be == here instead of >=, but I'm not familiar with the string and SOS states. I wonder if any display files sent from the BBS would ever include those sequences.
