Introduction

Quatech RS232 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. In addition, their small size and the fact that the card itself can be left inside the computer at all times, make them practical choices for the most ported portable systems.

Quatech RS-232 serial PCMCIA cards are designed to provide maximum performance while taking up minimal system resources. For high performance is heavy multitasking environments, the cards are implemented with 16750 UARTs containing 64-byte FIFOs. This along with Quatech's special clock-multiplying feature enables data transfer rates as high as 921.6 kbps. (4-port cards still use 16550 UARTs for standard 115.2 kbps speeds, but are due for an upgrade soon.) The cards also conserve system resources with their low power requirements that maximized battery life. They also have selectable and shareable interrupts, further extending a portable or handheld system's limited resources. And their multi-platform operating support makes them the single practical choice for a diverse fleet of portable systems.

Specification
Bus Interface:

16-bit PCMCIA, Release 8 & backward compliant (works in cardbus slots as well)

OS Support:

Windows CE/9x/Me/NT/2000/XP/VISTA, OS/2
Linux support via card/socket services for Linux
Data Rate:

All units: 921.6 kbps (max)
Serial Ports:

SSP:1
