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. |
