On a windows one would have to close the connection every time then since that
OS only allow _one_ connection to the serial ports.

I�ve been it around, as I wrote in the first mail, but something must have been
misspelled by me, cause I took the example from fgetc:
$fp = fopen("COM1", "w+b");
while (false !== ($char = fgetc($fp))) {
echo ".$char";
}
And nothing happened, so I figured that the switch might me locked somehow, I
turned it off and on again and suddenly all the start up info from the switch
was shown on my screen. I now use the example as a wrapper:
// open connection
$fp = fopen("COM1", "w+b");
// listen for output from $fp
while (false !== ($char = fgetc($fp))) {
// save chars in buffer, if NOT returns or newlines
if($char != "\r" && $char != "\n") {
$buffer .= $char;
// We need to know if things went wrong
if(trim($buffer) == "Error")
$response[] = "Error";
// execute commands
if(trim($buffer) == "SecOff >") {
$command = "$Sec[$SecOff]\r\n";
fwrite($fp, $command);
print "writing: $command\n";
$SecOff++;
$buffer = "";
}
}
I�m working on it as we speak, this is just a part of the script. It�s so nice
to have a break through finally :-)

I know, that�s how I�ve done it. During try&fail tests I�ve tried like
everything. My mistake to not check the code properly before mailing it here...
Have a nice weekend out there :o)
