Terminal Handling by kmdb

kmdb always uses the system console for interaction.

kmdb determines the appropriate terminal type according to the following rules:

• If the system being debugged uses an attached keyboard and monitor for its console and the debugger is loaded at boot, the terminal type is determined automatically based upon the platform architecture and console terminal settings.

• If the system being debugged uses a serial console and the debugger is loaded at boot, the default terminal type is vt100.

• If the debugger is loaded by running one of the mdb -K commands on the console, the debugger uses the value of the $TERM environment variable as the terminal type.

  For information about the various mdb -K commands, see kmdb Debugger Entry.

• If the debugger is loaded by running one of the mdb -K commands on a terminal that is not the console, the debugger uses the terminal type that is configured for use with the system console login prompt. When you run this command from the terminal, you must include the -F option on the command line.

  For information about the -F option, see the mdb(1) man page.

You can use the ::term dcmd from within kmdb to display the terminal type.
