PureBasic - SerialPort
The Serial port (also know as the RS-232 port) was first created in 1969, and despite its age, it is still widely used in the industry. The process of computer driven hardware prototype creation is simplified when the serial port is used. This library offers full access to the serial ports available on the computer. Some basic knowledge about the terms used in this documentation will be needed, check Wikipedia - RS232 for more information.
