Answer 1

This is a useful class for serial attatched devices on Linux: PHP Serial

Serial ports are often used to communicate with peripheral devices, such as: modems, POS terminals, special printers, etc..

This class can be used to communicate and configure peripherals connected to a serial port under Linux, simplifying the development of applications that need access serial devices.
