3.2.9 MCR - Modem Control Register (R/W) 

 

The Modem Control register controls the interface with the modem or data 
set as described below.  

For model AP512, RTS is used to enable the transceiver to enable output of 
TxD.  The four modem control inputs (CTS, DSR, DCD, and RI) are 
disconnected from their receiver input paths.  In addition, the four modem 
control outputs (DTR, RTS, OUT1, and OUT2) do not have transmitter output 
paths. 

Bit-

3 of this register must be set to a logic “1” to enable the corresponding 

port to issue an interrupt.
