# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.
#
# In particular, this should not be used as an example of modern Perl
# programming techniques.
#
# Suggested alternative: Term::Cap
#
;#
;# Usage:
;#      require 'ioctl.pl';
;#      ioctl(TTY,$TIOCGETP,$foo);
;#      ($ispeed,$ospeed) = unpack('cc',$foo);
;#      require 'termcap.pl';
;#      &Tgetent('vt100');      # sets $TC{'cm'}, etc.
;#      &Tputs(&Tgoto($TC{'cm'},$col,$row), 0, 'FILEHANDLE');
;#      &Tputs($TC{'dl'},$affcnt,'FILEHANDLE');
