J2, which is the 5×2 DTR/DSR header for the RS422 channel on the evaluation board. The OX16PCI952 supports one RS422 port. Data transfer rates are much greater using RS422 protocol, because it uses differential signalling. However, RS422 connectors only allow for CTS/RTS flow control. J2 provides access to the hardware lines necessary to provide DTR/DSR flow control in addition to conventional CTS/RTS flow control. -

Page 16: Interrupts
OX16PCI952 Evaluation Board User Guide Interrupts Interrupts in PCI systems are level-sensitive and can be shared. In the OX16PCI952, there are five interrupt sources—one from each UART channel, two from multi-purpose I/O pins (MIO0 and MIO1), and one from the parallel port. -
Page 17: Appendix A Drivers
Drivers Reference drivers and utilities for the Oxford Semiconductor UART products are supplied to demonstrate functionality under Windows operating systems. These drivers have been tested using Oxford Semiconductor development boards in a range of PC systems. Driver software and any accompanying files are provided ‘as is’ and without warranties as to performance or merchantability, or any other warranties whether express or implied. -
