fsockopen / fwrite / fgets problems...

[Skeets]

i'm having some php problems.

i have the following code on my main page:

------------
$fp = fsockopen("127. 0.0.1", 49152, $errno, $errrstr, 30);
if (!$fp)
{
echo "socket error: $errstr ($errno)<br />\n";
die;
}

$s_mode = GetParam ($fp, ANALOG_MODE);
------------

i have the following function:

------------
function GetParam ($fp, $param)
{

if (!$fp)
{
echo "get parameter error: $errstr ($errno)<br />\n";
return;
}

$cmd = '@B3,' . $param . '<nl>';

fwrite ($fp, $cmd);

$result = fgets ($fp, 128);

//echo 'Result: '.$result; die;
//echo "got $result in funciton\n";
list($cut, $keep) = explode('', $result);
list($keep, $cut) = explode('<nl', $keep);
//echo 'res'.$result.' res';
return $result;
}
------------

this function appears to be blowing a gasket somewhere around fwrite or
fgets. when i try to print $result, i get the error:

Result: @ERR:args_too_l ong

does anyone have any know what the problem is or how to troubleshoot
this?

Looks like whatever you're trying to write to is returning an error message.
What's listening on socket 49152?
