Update of /cvsroot/src/sys/arch/i386/isa
In directory netbsd1:/var/slash-tmp/cvs-serv27144

Modified Files:
        pccons.c 
Log Message:
Fix the problem described in PR port-i386/4177: scroll lock could cause
tsleep() to be called from an interrupt handler.
The semantics of the scroll-lock key is changed now: it issues a ^S or
^Q, depending on the current state. (It should probably issue
tp->t_cc[VSTOP] or tp->t_cc[VSTART] instead, but this would require more
serious structural changes because there is not always a tty context
present.)
The "scroll lock" LED is now controlled by pcstart()/pcstop(), so it
will show the real state even if the start/stop characters are remapped
or the normal ^S/^Q are used.
