Serial ConnectorSerial connectors support devices such as external modems, printers, and mice that require serial data transmission. The serial connector uses a 9-pin D-subminiature connector.Serial Connector AutoconfigurationThe default designation of the integrated serial connector is COM1. When you add an expansion card containing a serial connector that has the samedesignation as the integrated connector, the system's autoconfiguration feature remaps (reassigns) the integrated serial connector to the next availabledesignation. Both the new and the remapped COM connectors share the same IRQ setting. COM1 and COM3 share IRQ4, while COM2 and COM4 share IRQ3.Before adding a card that remaps the COM connectors, check the documentation that came with the software to make sure that the software canaccommodate the new COM connector designation.Figure B-2 illustrates the pin numbers for the serial connector and Table B-2 defines the pin assignments for the connector.Figure B-2. Serial Connector Pin NumbersTable B-2. Serial Connector Pin AssignmentsParallel ConnectorThe integrated parallel connector, intended primarily for use by printers that require data in parallel format, uses a 25-pin D-subminiature connector on thesystem's back panel. The default designation of the system's parallel connector is LPT1. If you add an expansion card containing a parallel connectorconfigured as LPT1 (IRQ7, I/O address 378h), use the System Setup program to remap the integrated parallel connector. See "Using the System SetupProgram" in the User's Guide. Figure B-3 illustrates the pin numbers for the parallel connector and Table B-3 defines the pin assignments for the connector.Figure B-3. Parallel Connector Pin NumbersNIC connectorNOTE: If two COM connectors share an IRQ setting, you may not be able to use them both at the same time. In addition, if you install one or moreexpansion cards with serial connectors designated as COM1 and COM3, the integrated serial connector is disabled.Pin Signal I/O Definition1 DCD I Data carrier detect2 SIN I Serial input3 SOUT O Serial output4 DTR O Data terminal ready5 GND N/A Signal ground6 DSR I Data set ready7 RTS O Request to send8 CTS I Clear to send9 RI I Ring indicatorShell N/A N/A Chassis ground
