Miscellaneous notes:
#define XBBS and the program will be compiled to read ONLINE.XBS
#define DORINFO and the program will be compiled to read DORINFO?.DEF
#define both and first ONLINE.XBS will be read, then DORINFO?.DEF
(don't know why you'd wanna do that)
#define neither and all info must come from command line
#define FINDUSER and a routine to find a given user (by name) will
be compiled in (finduser()) for XBBS' USERS.BBS
#define NOREADFILE and the file reader routine (readtext()) will NOT
be compiled
#define DISABLEBREAK to disable CTRL-BREAK/CTRL-C
#define DIALTRANS to include code for sending modem control strings
set chars to be unsigned by default
recommend large model (recompile screen2.asm and ansi.asm if other)
this code requires a FOSSIL for serial i/o--see function fossil()
