The OMG-COMM232-EX is a PC
bus plug-in card based on the
16550 FIFO buffered UART, which
is compatible with the standard
8250. This dual channel
asynchronous serial communication
card utilizes the RS-232
specification to provide RS-232
communication capabilities to your
application. Selectable and sharable
extended “AT” interrupts increase
the OMG-COMM232-EX versatility.
Signals are transmitted and
received via two 9-pin
sub-D male connectors.
Bit character lengths of
5, 6, 7 or 8, and odd, even
or no parity are all available.
WIN 95/98/Me/NT/2000/XP drivers
are included as well as support for
Linux, QNX and DOS. The drivers
provide IRQ sharing, advanced
UART support and serial
diagnostic utilities.
