Clear To Send is the modem control input.
The function of these pins can be tested by reading Bit 4 of the
handshake status register.
Data Set Ready. An active low indicates the modem or data set is ready
to establish a communication link and transfer data to the UART.

I
Serial Input. Used to receive serial data from the communication link.
SINB can be programmed by CR0D register as input pin IRRX1 for
serial infrared communication
UART A Serial Output. Used to transmit serial data out to the
communication link.
During power-on reset, this pin is pulled up internally and is defined as
HURAS1, which is used for selecting the I/O address of the UART A.
(See Table 1-2.)
UART B Serial Output. Used to transmit serial data out to the
communication link. SOUTB can be programmed by CR0D register as
output pin IRTX1 for serial infrared communication.
During power-on reset, this pin is pulled up internally and is defined as
HURBS1, which is used for selecting the I/O address of UARTB. (See
Table 1-2.)
UART A Data Terminal Ready. An active low informs the modem or
data set that the controller is ready to communicate.
During power-on reset, this pin is pulled down internally and is defined
as HPRTAS0. It is used for selecting the address of the parallel port.
(See Table 1-3.)
UART B Data Terminal Ready. An active low informs the modem or
data set that controller is ready to communicate.
During power-on reset, this pin is pulled down internally and is defined
as HURAS0. It is used for setting the I/O address of UART A. (See
Table 1-2.)
