Quatech RS-232 asynchronous serial PCMCIA cards are an ideal solution for adding additional ports to a wide variety of
portable systems. These cards share fundamental design architecture similar to PCI and ISA so that they function exactly like
the standard COM port(s) on system motherboards.
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.
The card also conserve system power to help maximize battery life.
It also has selectable and shareable interrupts, further extending a portable or handheld system's limited resources.
