Refer to the description of the parallel port for the definition of this pin in ECP
and EPP mode.
IDE Secondary Channel Chip Select.
Data Set Ready. This active low input is for the UART ports. A handshake
signal notifies the UART that the modem is ready to establish the
communication link. The CPU can monitor the status of the DSR_n signal by
reading bit5 of the Modem Status Register (MSR). A DSR_n signal states the
I
change from low to high after the last MSR read sets bit1 of the MSR to a “1”.
If bit 3 of the Interrupt Enable Register is set, the interrupt is generated when
DSR_n changes state.
Note: Bit 5 of the MSR is the complement of DSR_n.
