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.
