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 successful and the configuration actually went fine :-)
doing:
$fp = fopen("COM1", "rwb");
fwrite($fp, $username . "\r\n");
fwrite($fp, $password . "\r\n");
works fine, if I connect using hyperterminal afterwards I'll go straight to the menus, which shows that I'm logged in and I can actually config the whole device as I want, but I'd like to know, that each of the commands was received successful. But if I try to do something like :
$fp = fopen("COM1", "rwb");
fwrite($fp, $username . "\r\n");
$response = fread($fp, 4096); // is blank! Should return "Password: "
if($response == 'password')
fwrite($fp, $password . "\r\n"); // Would be lovely if it was able to read the return answer "Manager >" :-) else {
print "no response?";
exit;
}
This is where it ends. I´ve tried with fputs(), fgets(), fgetc(), popen() and others. It seems like what I need is a fwrite(), that doesn't return no of bytes, but the response from the device if any.
Anyone got an idea? Or is this just mission impossible? This is just a small part of a much larger workflow, which runs in PHP, therefore it would be preferred if the configs of switches and routers could be in PHP aswell.
