Subject: Re: Telnet Ruby

Thanks Brian!

The problem is that "I might have two possible prompts in response to 
one command"

When I execute the command "go" on Telnet, I can either get the:
prompt 1: BDI> (or)
prompt 2: - TARGET: stopped \n BDI>

When I get prompt 1, I want it to send in the instructions:
"re"
"ci"
"bi 0x000044bc"
"go 0"

However when i get prompt 2, i want to send in the instructions:
"dump 0x003f7670 128 C:/Dump/atl.dat"
"go".

Based on ur suggestion I modified the code to (also attached):
-------------------------------------
class RBDI_test

  attr_accessor :quiet

  def initialize(options)
    @prompt = /- TARGET: stopped \n BDI>|BDI>/
    @quiet = options['Quiet']
    @quiet = true if @quiet.nil?

    @connection = Net::Telnet.new({'Host'   => options['Host'],
                                   'Prompt' => @prompt}) {|str| print 
str unless @quiet}

    # consume the initial display of help
    @connection.waitfor(@prompt) {|str| print str unless @quiet}
  end

  # Send a script of commands to the BDI
  # If script is a filename, the commands will be read from the file.
  # The Quiet option specified at creating may be overruled for this 
script.
  def send(script, options={'Quiet' => @quiet})
    script = File.new(script) if FileTest.file? script

    begin
      script.each_line do |command|
        @connection.cmd(command.strip) do |str|
          print str unless str.nil? or options['Quiet']
        end
      end
    rescue Errno::ECONNRESET, Errno::ECONNABORTED
      puts "Connection closed" unless options['Quiet']
      return
    end
  end

end
------------------------
AND
----------
require 'rbdi_test'

bdi = RBDI_test.new({'Host'  => 'bdiemul'})
bdi.quiet = false

bdi.send("Prompt"=>/BDI>/) <<-LOAD_SCRIPT
re
ci
bi 0x000044bc
go 0
LOAD_SCRIPT

j = true

while j

bdi.send("Prompt"=>/- TARGET: stopped \n BDI>/) <<-LOAD_SCRIPT
dump 0x003f7670 128 C:Dump/atl.dat
go
LOAD_SCRIPT

end

sleep 1
-------------------------

I end up with the error:
C:/load565-released/test.rb:18: syntax error, unexpected tINTEGER, 
expecting kEND
dump 0x003f7670 128 C:Dump/atl.dat

Amogh.
