9.4.17
Modem Change Option Register 2
This register is used to define the current state change options to be monitored.
9.4.18
Modem Signal Value Register
This register is read to determine the current input levels on the Modem Input pins. It is written to
supply an output value for the RTS* and DTR* pins. The register bits have the opposite polarities
from the actual states on the individual pins. Writing a
1
causes the pin to go to nominal zero
volts.
