Description
Quatech RS-232 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. |
