/***************************************************************
* vt100 - terminal emulator - initialization
*
* v2.7 870825 ACS - Allow execution of all script files specified on
* command line (companion to changes in script.c).
* Rolled menu init into one routine (do_menu_init()).
* v2.6 870227 DBW - bug fixes for all the stuff in v2.5
* v2.5 870214 DBW - more additions (see readme file)
* v2.4 861214 DBW - lots of fixes/additions (see readme file)
* v2.3 861101 DBW - minor bug fixes
* v2.2 861012 DBW - more of the same
* v2.1 860915 DBW - new features (see README)
* 860901 ACS - Added Parity and Word Length and support code
* 860823 DBW - Integrated and rewrote lots of code
* v2.0 860809 DBW - Major rewrite
* v1.1 860720 DBW - Switches, 80 cols, colors, bug fixes
* v1.0 860712 DBW - First version released
