ttytype(1) Support for the N4000 Console
The ttytype (1) command has been enhanced to support the N4000 console. However,
there are no user-visible changes in the behavior of the command.
A new ioctl()call is 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.
New stty(1) Options
Two new options have been added to the stty command to support the console on the
N4000, L-Class and N-Class systems:
+queryGSP Query the status of the GSP (Guardian Service Processor).
+resetGSP Reset 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 directing the command at the console device:
stty +resetGSP < /dev/GSPdiag1
These options require superuser status.
