I am tired of working with Serial comport to send and receive data ( Windows ). I have tried every possible way. Every time i got able to connect and send data. But when it comes to receiving lines script got hanged.

I am sure device which is connected to comport is working as it returned data when reading through windows power shell.

In my readings about PHP, two important things to know, 1) PHP opens and closes the serial port when it sends something to the serial port, so the arduino auto reset will need to be defeated, and 2) PHP does not have any way to receive data from the arduino via the serial port. I am tired of working with Serial comport to send and receive data ( Windows ). I have tried every possible way. Every time i got able to connect and send data. But when it comes to receiving lines.

There are two most common methods i have tried are:

1 PhpSerial.php ( Line: 597 )

2 Direct-Dio library

By using Direct-Diogetting Hanged on > $data = dio_read($bbSerialPort, 1024);

I din't find any solution on internet.

I am trying to connect weighting machine with PHP.

I have tested with hyperterminal it is working fine.

But when I use PHP code with fopen or dio_open it is executed but when fgets or dio_read is called, it hangs and does not display anything.

DIO Example

I'm unable with my tries of both ways to gather any useful output.

Do I require inpout32.dll file to connect?

And what is role of php_iol.dll, this file I also required?

PHP can not read from serial ports under Windows. This is not the case on a Linux system, on which there is no problem to reading from COM ports with the common PHP filesystem functions.

Those filesystem functions are also the preferred ways to do in regard of the DIO extension:

The use of the DIO functions should be considered only when direct control of a device is needed. In all other cases, the standard filesystem functions are more than adequate.

As you report your DIO example as 'non-working', you need to keep track of errors. See:

Next to that you need to find a working POSIX example first, as DIO is not hyperterminal but POSIX style.

Alternatively some software exists to proxy a COM port through network (for example GPL'ed serproxy). This might solve you integration problem with your operating system, however I'm pretty sure you're out of luck.
