The OMG-COMM2-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 balanced differential drivers and receivers to provide RS-422
and RS-485 communication. Selectable and sharable extended "AT" interrupts for each
port increase the OMG-COMM2-EX versatility. Distances of 5000 ft. in noisy industrial
environments are easily accommodated. The OMG-COMM2-EX is also capable
of RS-232 for applications requiring shorter distances and RS-232 compatibility. Signals
are transmitted and received via two 9-pin sub-D connectors. Bit character lengths of 5, 6,
7 or 8, and odd, even or no parity are all available.
For those users creating their own DOS based programs, the
OMG-COMM2-EX includes a serial communication software driver which provides fully
buffered interrupt driven input and output to multiple asynchronous serial communication
ports. The driver is a BIOS extension and/or replacement that provides extended
capabilities in the form of block I/O and user configurable flow control support in addition
to emulating standard BIOS interrupt 14h calls. The Driver supports C, C++ and BASIC.
