debug − enter remote debugging mode [ -r ] console_device cause the debug monitor to enter a mode where it expects remote debugging requests via the serial port indicated by Currently, the UMIPS-BSD symbolic debugger "dbx" can communicate with dbgmon via this protocol.  The protocol spoken via the debug command is a machine to machine protocol and thus the debug command is useful only for establishing communication with remote debuggers.  Debug mode may be exited by entering a control-z to the console of the system running dbgmon.  Dbgmon will re-enter command mode and system state that may not be examined remotely (e.g. tlb contents) can be displayed.  Debug mode may be resumed by using the debug command with the -r flag.  The -r flag causes dbgmon to re-enter debug mode without reset its protocol sequence counters.  If you intend to resume debug mode with a remote debugger, debug mode should only be exited via a control-z when the client process is stopped and the remote debugger is waiting for command input.  Debug mode may be aborted at any time with a control-c.  debug(5spp), dbx(1), slp(5spp)
