Thanks -- I'll look at POE. As for example client code, it is just unbelievably {and unfixably} dumb:
sub command
{ my $cmd = "$_[0]\r\n" ;
print $server $cmd ;
my $resp = <$server> ;
return undef if $resp !~ /^[123]/ ;
return $resp ;
}
I don't even remember what got me thinking that IO::Socket's can be used as file descriptors {I just looked and can't find it in the man pages..sigh} I guess what I can do is do a 'send' with the $cmd my sub is given and then I need to replace the <$server> with something that'll timeout and then I can close/reopen the socket and try again. POE seems fancier than I need for this {although I see that it can handle the event loop of Tk, something I had trouble getting to work correctly}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
