The Comtrol RocketPort USB Modem is part of the RocketPort family of serial communication devices developed by Comtrol Corporation. RocketPort devices are used to add additional serial ports (RS-232, RS-422, or RS-485) to a computer via USB or other interfaces. The USB version of RocketPort allows you to connect serial devices, such as modems, industrial equipment, or network routers, to a computer via a USB port.
The Comtrol RocketPort USB Modem Windows driver is software that enables your computer to communicate with the RocketPort USB device, allowing it to function as an additional serial port for connecting various devices. These devices could include modems (analog or digital), point-of-sale (POS) systems, or industrial automation equipment.
