read FROM com1

[Kim Madsen - ComX]

Hi

I´m having trouble reading from COM1, writing works like a charm but I´d
like to be able to read the output from a switch or a router in order to
determine that the command was succesful and the configuration actually
went fine :-)

doin´:

$fp = fopen("COM1", "rwb");
fwrite($fp, $username . "\r\n");
if($response == 'password')

works, using hyperterminal shows that I´m logged in and i can actually
config the device as I want, but if I try to do something like :

$fp = fopen("COM1", "rwb");
fwrite($fp, $username . "\r\n");
$response = fread($fp, 4096);
if($response == 'password')
fwrite($fp, $password . "\r\n");
else {
print "no response?";
exit;
}

this is where it ends. Anyone got an idea?

The example from the manual on fgetc works when used as a wrapper:

$handle = fopen("COM1", "r");
while (!feof($handle) ) {
$buffer = fgets($handle, 4096);
// do the stuff You wanna do
echo $buffer;
}
fclose($handle) ;

When starting this script nothing happend, so I figured that the switch
might be locked somehow and I turned it off and on again, then all start
up info FROM the switch was shown on my screen...
