Page 5: Introduction
Overview The Omega Engineering OMG-COMM+232.PCI is a two channel PCI Bus serial I/O adapter for the PC and compatibles. It provides two RS-232 serial ports supporting data rates up to 460.8K bps. The OMG-COMM+232.PCI works seamlessly with the standard operating system serial driver. -
Page 6: Card Setup
Card Setup Card Setup Address and IRQ selection The OMG-COMM+232.PCI is automatically assigned I/O addresses and IRQs by your motherboard BIOS. Only the I/O address may be modified by the user. Adding or removing other hardware may change the assignment of I/O addresses and IRQs. -

Page 12: Technical Description
Technical Description Technical Description The Omega Engineering OMG-COMM+232.PCI provides a PCI interface adapter with 2 asynchronous serial ports providing a versatile interface for modems, printers and plotters. The OMG-COMM+232.PCI utilizes the 16550 UART. This chip features programmable baud rates, data format, interrupt control and a 16-byte input and output FIFO. -

polling’. This method required the interrupt service routine to ‘poll’ or interrogate each UART as to its interrupt pending status. This method of polling was sufficient for use with slower speed communications, but as modems increased their throughput abilities this method of servicing shared IRQs became inefficient. -

Page 17: Appendixc - Electrical Interface
Appendix C – Electrical Interface Appendix C - Electrical Interface RS-232 Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard. -
Page 18: Appendixd - Asynchronous Communications
Appendix D - Asynchronous Communications Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends. -
