Can I read/write to the Serial Port, Comm1 or Comm2 using PHP?

GG
I don't know if this can be done. Can PHP be used to read/write to the
serial port on a PC? Any replies related to Linux or Windows are
welcome.

Ultimately, I would like to be able to send a character string to the
serial port when a button is clicked on a PHP driven website.

Any thoughts anyone?

My first thought is http://www.php.net/manual/en/ref.dio.php

On Windows, try fopen("com1", "wb") and write to the handle returned.

I was hoping for a cross platform solution but both yours and Urs' do
not give me enough information to proceed.

Does anyone else have any suggestions and can provide me with more
detail?
Thanks.
