2000-08-21 OKUJI Yoshinori <okuji@gnu.org>
* configure.in (--enable-serial-speed-emulation): New option.
(SERIAL_SPEED_SIMULATION): New conditional.
* grub/Makefile.am (SERIAL_FLAGS): New variable. Set
-DSUPPORT_SERIAL=1 and -DSIMULATE_SLOWNESS_OF_SERIAL=1, if
SERIAL_SPEED_SIMULATION is defined, otherwise, set it to
only -DSUPPORT_SERIAL=1.
(AM_CFLAGS): Removed -DSUPPORT_SERIAL=1 and added
$(SERIAL_FLAGS).
* grub/asmstub.c [SIMULATE_SLOWNESS_OF_SERIAL] (serial_speed):
New variable.
(grub_setjmp): Removed.
(grub_longjmp): Likewise.
(serial_getkey) [SIMULATE_SLOWNESS_OF_SERIAL]: Wait for
1000000 / (SERIAL_SPEED >> 3) microseconds using gettimeofday.
(serial_putchar) [SIMULATE_SLOWNESS_OF_SERIAL]: Likewise.
(serial_init) [SIMULATE_SLOWNESS_OF_SERIAL]: Set SERIAL_SPEED to
SPEED.
* stage2/builtins.c (serial_func) [SUPPORT_SERIAL]: Added
a new option, `--speed'.
(builtin_serial): Added a description about --speed.
(terminal_func): When get a key from a serial device, if GRUB is
in the command-line interface, call grub_longjmp with
RESTART_CMDLINE_ENV, instead of init_page.
* stage2/cmdline.c (restart_cmdline_env): New variable.
(enter_cmdline): Call grub_setjmp with RESTART_CMDLINE_ENV after
calling init_cmdline.
(run_script): Run BUILTIN->FUNC with BUILTIN_SCRIPT instead of
BUILTIN_CMDLINE.
* stage2/shared.h (BUILTIN_SCRIPT): New macro.
[GRUB_UTIL] (grub_setjmp): Defined as setjmp.
[GRUB_UTIL] (grub_longjmp): Defined as longjmp.
(restart_cmdline_env): Declared.
