Description
Clear To Send is the modem control input.
Data Set Ready. An active low signal indicates the modem or
data set is ready to establish a communication link and transfer
data to the UART.
UART 6 Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
UART 6 Data Terminal Ready. An active low signal informs
the modem or data set that controller is ready to communicate.
Serial Input. Used to receive serial data through the
communication link.
