Almost all PA-RISC machines have either a button that
is labeled with 'TOC' or a BMC function to trigger a TOC.
TOC is a non-maskable interrupt that is sent to the processor.
This can be used for diagnostic purposes like obtaining a
stack trace/register dump or to enter KDB/KGDB.
As an example, on my c8000, TOC can be used with:
CONFIG_KGDB=y
CONFIG_KGDB_KDB=y
and the 'kgdboc=ttyS0,115200' appended to the command line.
Press ^[( on serial console, which will enter the BMC command line,
and enter 'TOC s':
