The OMG-COMM8-PCI plugs 
into any IBM or compatible 
computer with the PCI bus, 
and provides 8 RS-232 Async 
ports for communication servers, 
terminals, point of sale (POS) 
systems, and other data collection 
devices. The on-board interrupt 
status port provides maximum 
Windows flexibility. The OMGCOMM8-PCI includes the 16554 
UART, providing a 16 byte FIFO 
to keep your data communication 
applications running error free. 
The 16654 UART, featuring a deep 
64 byte FIFO is optional for high 
speed applications.
