Author: jcrouse Date: 2008-08-11 22:34:28 +0200 (Mon, 11 Aug 2008) New Revision: 3499
Modified: trunk/payloads/libpayload/curses/tinycurses.c trunk/payloads/libpayload/drivers/serial.c trunk/payloads/libpayload/include/libpayload.h Log: Add support for line drawing characters and the alternate character set. This enables using the ACS_ curses macros with libpayload.
The translation from ACS_ macros (or characters with attribute A_ALTCHARSET) is done using one acs map for the video console, one for serial console (xterm/vt100/vt220), and one fallback, from which an ASCII substitute is taken if the device specific map doesn't contain an entry (ie NUL).
