NAME

       twiglet - observe or control an RVC-enabled machine's console

SYNOPSIS

       twiglet [OPTION]... host-specification

DESCRIPTION

       twiglet	is a program for controlling another machine's console.  It works using the RVC protocol, and an RVC server (such as rvcd(1)) must
       be running on the machine to be observed.

       Using twiglet, the a best effort attempt is made to duplicate the screen contents of the observed machine.  If the machine is displaying  a
       virtual	text  console,	the text on the console is rendered in the terminal in which twiglet runs.  If the machine is displaying an X ses-
       sion, and the RVC server supports VNC integration, twiglet will open a window that contains the current contents of the X display.

       It is also possible to control the observed machine in various ways.  With keyboard control enabled (and with support from the RVC server),
       keys  may  be  sent  to	the  observed  machine in text console mode almost as if they were typed from the keyboard.  Twiglet also supports
       switching virtual console on the observed machine.  Finally, if VNC integration is available, the X display can be manipulated almost as if
       the user were at the console.

       The  intended  use for twiglet is in training and teaching environments.  The idea is that there are student machines and a control machine
       (which the trainer or teacher would be using), with a serial line attached to each student machine.  The trainer or teacher can	then  ana-
       lyse  the  students' attempts to complete tasks, and help them out (showing them how to finish it) without needed to push them aside to get
       to the keyboard.

       This client is written using ncurses(3X).

OPTIONS

       --help display a help message and exit successfully

       --version
	      display a version number and exit successfully

       -c, --control
	      control the remote machine rather than just observing it

       -e xy, --escape xy
	      set the escape character and the escape escape character (like screen(1))

       The host-specification takes one of the following forms:

       host:port
	      to connect to an RVC server over TCP

       tty [host]
	      to communicate with an RVC server over a tty (for example a serial line); the optional hostname is for VNC integration

BUGS

       I'm sure there are bugs, but I don't know what they are.

NAME

       conspy - virtual console spy tool

SYNOPSIS

       conspy [ options ] [ console ]

DESCRIPTION

       Conspy  allows the user to take control of a Linux virtual console.  The user can see what is displayed on the console and their keystrokes
       are sent to it.

       To exit from conspy press the escape key three times in quick succession.

COMMAND LINE

       -V, --version
	      Print the program's version and exit.

       -v, --viewonly
	      Don't send keystrokes to the virtual console.

       console
	      If supplied, console must be a number in the range 1 .. 63, corresponding to the virtual console device /dev/tty1 .. /dev/tty63.	If
	      not supplied the currently active virtual console is opened and tracked.

LIMITATIONS

       Conspy will not pass keystrokes to a virtual console whose keyboard is configured to send scan codes.  X configures its keyboard like this.
       If the terminal does not have at least 64 colours no colour will be displayed.  Conspy ignores the mouse.  Conspy  may  display	some  non-
       ASCII characters incorrectly.  Conspy does not handle displays larger than 16000 characters (eg 200 rows x 80 columns).

       Conspy  depends	on terminfo and curses working correctly for your terminal, and sometimes they don't.  Konsole is/was one example of where
       they don't.  Typing control-L will redraw the screen, which usually fixes the mess created.  It also sends a control-L to the virtual  con-
       sole, of course.

FILES

       /dev/ttyX, /dev/vc/X
	      The characters typed are sent to this device.  The latter is for devfs. It is only used if the former does not exist.

       /dev/vcsaX, /dev/vcc/aX
	      The display of the virtual console is read from here.  The latter is for devfs. It is only used if the former does not exist.
