Net ssh users - Jun 2007 - Sending non-string charachters

Essentially I want a way to send a command the the remote host and when
I see a certain string I want to break it by sending a CTRL-C

Think tail -f running until I see a string I care about.

Is there a way to do this?

I''m also using the ruby serialport library and sending a ctrl-c is as
simple as serial_port.putc(3) - they ASCII code for ctrl-c.

I couldn''t figure out a way to do it directly, so my hack involved
something like this:

Signal.trap ("INT") do
      kill_executable($pathToExecutable)
end

def kill_executable($path)
   start a new net::ssh connection
   create a new shell using: shell = session.shell.async
   out = shell.killall "-INT $path"
   shell.exit
end

Thanks,

I ended up with an indirect way as well-

def send_non_sync cmd
     @session.process.open(cmd) do |command|
       command.on_success do |p|
         @log.debug "#{cmd} Succeeded"
       end

       command.on_stdout do |p,data|
         yield data
       end

       command.on_exit do |p,status|
         puts "process finished with exit status: #{status}"
         return false
       end


     end
   end

which is kind of run as -
send_non_sync("tail -f /var/log/auth.log") { |output|
	grep on something in output and break...
     }
