I am just adding this information to the thread so that students can benefit: Almost all these devices are generically OS agnostic. Unless the device manufacturer has gone overboard to protect it from being used in Linux and/or has a proprietary protocol. Today most of them feature an USB interface. The USB interface is an USB/Serial convertor and almost all the convertors are supported by Linux. When you connect the device to the USB port of a linux box, a `usbserial` port gets listed in /dev (/dev/USBtty0 etc). Irrespective of OS, its just a matter of programming the serial port i/o to follow the manufacturer's published protocol.
