19. t Why use an ISP The answer to the polling inefficiency is the Interrupt Status Port ISP The ISP is a read only 8 bit register that sets a corresponding bit when an interrupt is pending Port 1 interrupt line corresponds with Bit DO of the status port Port 2 with D1 etc The use of this port means that the software designer now only has to poll a single port to determine if an interrupt is pending The ISP is at Base 7 on each port Example Base 280 Hex Status Port 287 28F etc The OMG COMM 232 PCI will allow any one of the available locations to be read to obtain the value in the status register Both status ports on the OMG COMM 232 PCI are identical so any one can be read Example This indicates that Channel 2 has an interrupt pending Bit Position 7 6 5 4 3 2 1 0 Value Read 0 10 10 0 0 0 1 0 Connector Pin Assignments RS 232 Name Pint Mode TD TransmitDaa 3 Output o RTS ReguestToSend 7 Output DTR Data TermReady 4 Output BONDE adi Z gt e RD ReceiveData 2 hpm DCD Data Carrier Detet 1 Input DSR DataSetReady 6 hpt CTS ClearToSend_ 8 pt RI Ringindicaor 9 omput Note These assignments meet ELA TIA ANSI 574 DTE for DB 9 type connectors Omega Engineering COMM 232 PCI Page 9 Specifications Specifications Environmental Specifications Temperature Range 0 to 50 C 20 to 70 C 32 to 122 F 4 to 158 F
