DESCRIPTION
Serial Port

Request
IRQ4 is the interrupt from the Primary Serial
Port (PSP) or Secondary Serial Port (SSP)
when the PSP or SSP have their address
programmed as COM1 or COM3 (as
defined in the Configuration Registers). The
appropriate interrupt from the Serial Port is
enabled/disabled via the Interrupt Enable
Register (IER). The interrupt is reset
inactive after interrupt service. It is disabled
through IER or hardware reset.
IRQ3 is the interrupt from the Primary Serial
Port (PSP) or secondary Serial Port (SSP)
when the PSP or SSP have their address
programmed as COM2 or COM4 (as
defined in the Configuration Registers). The
appropriate interrupt from the Serial Port is
enabled/disabled via the Interrupt Enable
Register (IER). The interrupt is reset
inactive after interrupt service. It is disabled
through IER or hardware reset.
This interrupt from the Floppy Disk
Controller is enabled/disabled via bit 3 of the
Digital Output Register (DOR).
