Filtering escape character from expect buffer
I have written an application in Tcl-Expect which spawns minicom and
sends and receives data via the serial port. Sometimes i see that the
application receives control characters along with human readable data.
A search on the internet tells me that the control characters are
nothing but the VT terminal codes. However i could not find a solution
to filter out the terminal codes.

I am attaching a sample of the expected buffer and the actual buffer.

Expected :-
Code:
Microsoft Windows [Version 6.2.9200](c) 2012 Microsoft Corporation. All rights reserved. C:\Windows\system32>


Actual:-
Code:
[1;1H[37m[40m [2;1H [3;1H [4;1H [5;1H [6;1H [7;1H [8;1H [9;1H [10;1H [11;1H [12;1H [13;1H [14;1H [15;1H [16;1H [17;1H [18;1H [19;1H [20;1H [21;1H [22;1H [23;1H [24;1H [1;1HMicrosoft Windows [Version 6.2.9200][2;1H(c) 2012 Microsoft Corporation. All rights reserved.[4;1HC:Windowssystem32>

http::cookies::microsoft

HTTP::Cookies::Microsoft(3)				User Contributed Perl Documentation			       HTTP::Cookies::Microsoft(3)

NAME

       HTTP::Cookies::Microsoft - access to Microsoft cookies files

SYNOPSIS

	use LWP;
	use HTTP::Cookies::Microsoft;
	use Win32::TieRegistry(Delimiter => "/");
	my $cookies_dir = $Registry->
	     {"CUser/Software/Microsoft/Windows/CurrentVersion/Explorer/Shell Folders/Cookies"};

	$cookie_jar = HTTP::Cookies::Microsoft->new(
			  file	   => "$cookies_dir\index.dat",
			  'delayload' => 1,
		      );
	my $browser = LWP::UserAgent->new;
	$browser->cookie_jar( $cookie_jar );

DESCRIPTION

       This is a subclass of "HTTP::Cookies" which loads Microsoft Internet Explorer 5.x and 6.x for Windows (MSIE) cookie files.

       See the documentation for HTTP::Cookies.

METHODS

       The following methods are provided:

       $cookie_jar = HTTP::Cookies::Microsoft->new;
	   The constructor takes hash style parameters. In addition to the regular HTTP::Cookies parameters, HTTP::Cookies::Microsoft recognizes
	   the following:

	     delayload:       delay loading of cookie data until a request
			      is actually made. This results in faster
			      runtime unless you use most of the cookies
			      since only the domain's cookie data
			      is loaded on demand.

CAVEATS

       Please note that the code DOESN'T support saving to the MSIE cookie file format.
