ESCDELAY and TABSIZE are extensions, not provided in most
other implementations of curses.

+ <STRONG>o</STRONG> In AIX, the units for ESCDELAY are <EM>fifths</EM> of a mil-
+ lisecond.
+
+ <STRONG>o</STRONG> The default value for AIX's ESCDELAY is 0.1 seconds.
+
+ <STRONG>o</STRONG> AIX also enforces a limit of 10,000 seconds for ESCDE-
+ LAY; this implementation currently has no upper limit.
+
+ This implementation has long used ESCDELAY with units of
+ milliseconds, making it impossible to be completely com-
+ patible with AIX. Likewise, most users have either decid-
+ ed to override the value, or rely upon its default value.
