ttytype Support for the N4000 and rp7400 Console
new at 11i
original release
Although the ttytype command has been enhanced to support the N4000 and rp7400
console, there are no user-visible changes in the behavior of the command.
However, a new ioctl()call has been added to the command to query the Guardian
Service Processor (GSP) console driver for the TERM identity. If the ioctl()call fails,
ttytype will continue with the existing terminal identification process.
For more information on the GSP, see “Service Processor (GSP or MP)” earlier in this
chapter. For information on the ttytype command, see the ttytype (1) manpage.
New stty Options
new at 11i
original release
Two new options have been added to the stty command to support the console on the
following systems:
• N4000
• all L-Class
• all N-Class
• rp2400, rp2450
• rp5400, rp5430, rp5450, rp5470
• rp7400
+queryGSP queries the status of the GSP (Guardian Service Processor)
+resetGSP resets the GSP of the console
Typically, you might use +queryGSP if you are getting no response at the console or
+resetGSP if the console locks up. Here is an example of the latter, which runs the
command elsewhere from the console but directs the command at the console device:
stty +resetGSP < /dev/GSPdiag1
Note that these options require superuser status.
For information on the stty command, see the stty (1) manpage.
