Last change on this file since 188 was 186, checked in by gregli@…, 13 years ago

Initial string compression checkin. All changes are under MODULE_STRINGS_COMPRESSED, and this can still be turned off. With this checkin, the serial and ebios code can both be turned on at the same time and still we remain below the 8K boundary (barely). I still need to chekin StringsCompress.pl after some more code cleanup. The output, in StringsCompressed.asm is checked in here, and should continue be to checkin when Strings.asm is changed, for those who do not have/want to run the Perl script to recreate it.
