Chapter 2: Touring the Chassis
6.
Edit the
/etc/inittab
file and change the word “off” to “respawn” in the
line associated with the
ttys
you have just enabled. :
Note:
Since there is no I/O panel connection for the RS-422 port (which
corresponds in this example to ttyd48), there is no reason to change it.
7.
Enter
telinit q
to force the init process to reread
/etc/inittab
and
create
gettys
on the additional RS-232 ports.
Device nodes of the form
tty[fm]*
are for use with modems. For additional
information on these topics, see the reference (man) pages for:
•
getty(1M)
•
uugetty(1M)
•
init(1M)
•
gettydefs(4)
•
inittab(4)
Note that comments in the file
/etc/inittab
are somewhat outdated and can be
potentially confusing as they refer to nomenclature and architecture of older
Silicon Graphics systems when referring to serial ports. When “I/O” board
is mentioned you should infer “VME serial I/O controller,” and where “CPU
board” is mentioned you should read “IO4 board.”
