Ah! i can't believe I missed the answer and it was IN the documentation! I'm so ashamed...What can i say, it was a very long workday. ::shrugs apologetically::
UPDATE: ok, this is kind of wierd, it seems that
everything is blocked from printing in the main loop until I ctrl+c, after which it all prints out and dumps back to command line.
while($EXIT == 0)
{
$temp = pollForData();
print $temp;
print LOG $temp;
sleep(1);
}
however, if i print the returned data
and include something else within the same print command, it works fine.
while($EXIT == 0)
{
$temp = pollForData();
print "$temp\n";
print LOG $temp;
sleep(1);
}
the thing is, i don't want to print the data every iteration through the loop, but otherwise NOTHING at all happens until i ctrl+c...OH, almost forgot. the
pollForData sub:
sub pollForData
{
my($length,$buffer);
# Poll controller to send any pending data (if there is none,
# it will send back a 'RES' control character
print SERIAL $IM{'POL'};
$upstream++;
# read in $BUFFER amount of bytes
$length = read(SERIAL,$buffer,$BUFFER);
# update num of bytes received so far
$downstream += $length;
# return data
return $buffer;
}

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>

-
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).
