Top Forums Shell Programming and Scripting How to send Ctrl Break combination in Expect Post 302388705 by JerryHone on Thursday 21st of January 2010 07:18:37 AM

Your control break selection will be mapped to a specific character or character sequence by the terminal handler to send to the remote device. You simply need to determine exactly what ASCII character(s) are being sent and replicate it on your expect send line.

You may be able to determine the sequence by turning on expect logging and going into expect interactive mode, so what you type is logged.

Hope that helps.

DISLOCATE(1)                                                  General Commands Manual                                                 DISLOCATE(1)

NAME
Dislocate - disconnect and reconnect processes SYNOPSIS
dislocate [ program args... ] INTRODUCTION
Dislocate allows processes to be disconnected and reconnected to the terminal. Possible uses: o You can disconnect a process from a terminal at work and reconnect from home, to continue working. o After having your line be dropped due to noise, you can get back to your process without having to restart it from scratch. o If you have a problem that you would like to show someone, you can set up the scenario at your own terminal, disconnect, walk down the hall, and reconnect on another terminal. o If you are in the middle of a great game (or whatever) that does not allow you to save, and someone else kicks you off the ter- minal, you can disconnect, and reconnect later. USAGE
When run with no arguments, Dislocate tells you about your disconnected processes and lets you reconnect to one. Otherwise, Dislocate runs the named program along with any arguments. By default, ^] is an escape that lets you talk to Dislocate itself. At that point, you can disconnect (by pressing ^D) or suspend Dislo- cate (by pressing ^Z). Any Tcl or Expect command is also acceptable at this point. For example, to insert the contents of a the file /etc/motd as if you had typed it, say: send -i $out [exec cat /etc/motd] To send the numbers 1 to 100 in response to the prompt "next #", say: for {set i 0} {$i<100} {incr i} { expect -i $in "next #" send -i $out "$i " } Scripts can also be prepared and sourced in so that you don't have to type them on the spot. Dislocate is actually just a simple Expect script. Feel free to make it do what you want it to do or just use Expect directly, without going through Dislocate. Dislocate understands a few special arguments. These should appear before any program name. Each should be sep- arated by whitespace. If the arguments themselves takes arguments, these should also be separated by whitespace. The -escape flag sets the escape to whatever follows. The default escape is ^]. CAVEATS
This program was written by the author as an exercise to show that communicating with disconnected processes is easy. There are many fea- tures that could be added, but that is not the intent of this program. SEE ALSO
