DESCRIPTION
nRing Indicator
Active low Ring Indicator input for primary
and secondary serial ports. Handshake
signal which notifies the UART that the
telephone ring signal is detected by the
modem. The CPU can monitor the status of
nRI signal by reading bit 6 of Modem Status
Register (MSR). A nRI signal state change
from low to high after the last MSR read will
set MSR bit 2 to a 1. If bit 3 of Interrupt
Enable Register is set, the interrupt is
generated when nRI changes state. Note:
Bit 6 of MSR is the complement of nRI.
In PS/2 mode, this input indicates whether a
second drive is connected; DRV2 should be
low if a second drive is connected. This
status is reflected in a read of Status
Register
A.
