A client asked for a web to fax application written in php. But I have no idea how to do this.
I believe php or any other web application can't communicate with the modem directly. So there should be some sort of service or daemon handling the job and be the line between web interface and modem.
Tried googling things a bit and some words like
AvantFax came out. Still can't figure out.
I prefer writing the web interface myself to have custom language support and better user experience.
So in the end what I am asking is how to achieve a web to fax application from scratch. From setting up server and making the web application. Even some directions would help.
