Description
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.
