Systems that use serial consoles don't necessarily provide support for those (fixed) control sequences. This can create really annoying problems, possibly locking up some terminals. The loader sources provide a compile-time #ifdef option (TERM_EMU) that enables this functionality, which is always enabled in the Makefile. >How-To-Repeat: n/a >Fix: Make the TERM_EMU option selectable in the Makefile. This is a diff on /usr/src/sys/boot/i386/libi386/Makefile. The same patch applies to /usr/src/sys/boot/pc98/libpc98/Makefile, but I have no way to test that. diff -u Makefile.orig Makefile --- Makefile.orig Tue Mar 25 14:58:31 2003 +++ Makefile Tue Mar 25 14:58:58 2003 @@ -29,7 +29,9 @@ .endif # Include simple terminal emulation (cons25-compatible) +.ifdef(NO_BOOT_TERM_EMU) CFLAGS+= -DTERM_EMU +.endif # Make "machine" required for all objects # (based on the more complete case in sys/i386/boot/Makefile.inc) >Release-Note: >Audit-Trail: >Unformatted:
