The Problem with some PCI Serial Cards.
BAD PROCESSOR CHIPS?! Does some serial port cards really have bad processor chips? ABSOLUTELY! Unless you invest in a PCI serial card with a quality processor and chipset you will very likely, at some point, experience either a computer freeze, driver errors, being unable to communicate with your serial device or even a BSoD. The reason is that most low-cost PCI serial cards are designed with a low-cost processor which has low-cost poorly written drivers, which obviously results in headaches for the user.
Our Premium RS232 PCI Serial card shown in the image above uses a quality processor (MCS9835) from MosChip Technology/ASIX which provides superior performance and reliability at unmatched data transfer rates.
The card adds two high-speed 9-pin serial COM ports to any PCI equipped (unlike USB based) computer with drivers available for DOS(!), Windows 98, 2000, XP, Vista, 7, 8, 8.1 and 10 32/64-bit.
After installing the downloadable drivers the created COM ports will automatically show up in your operating system's Device Manager as two additional ports. Since these ports are PCI based they can be used as if it was standard built-in COM ports.
Both RS232 serial ports share same IRQ which saves valuable resources if other expansion cards are used.
Easy Plug and Play installation automatically configures the next available COM port and IRQ address. COM ports can also easily be renamed within your operating system's Device Manager.
Connecting external modems, serial printers, handheld PDAs, mice and trackballs, keypads, serial POS devices, digital cameras and more has never been easier!
