Quatech RS-232 and RS-422/485 asynchronous serial PCMCIA cards are an ideal solution for adding additional ports to a wide variety of portable systems. Because they share electronic fundamentals with native bus architectures such as PCI and ISA, they function exactly like standard COM ports and can be addressed as such by most application software.

Quatech serial PCMCIA cards provide industry leading speeds of up to 921.6 kbps by employing a clock multiplying feature in conjunction with 16750 UARTs. To further increase performance, we have created an auto toggle feature for the RS-422/485 transmitter that permits the hardware itself to regulate data flow by only driving lines while actively transmitting--providing increased speed and convenience over the older software controlled method.
