Pin Description
SYMBOL DESCRIPTION
CTS* A/B
40,28
I
Clear to send A/B (active low). The CTS* signal is a
MODEM control function input whose conditions can be
tested by reading the MSR BIT-4. CTS* has no effect on the
transmit or receive operation.
DSR* A/B
41,29
I
Data set ready A/B (active low). A low on this pin indicates
the MODEM is ready to exchange data with UART. This pin
does not have any effect on the transmit or receive opera-
tion.
CD* A/B
42,30
I
Carrier detect A/B (active low). A low on this pin indicates
the carrier has been detected by the modem.
RI* A/B
43,31
I
Ring detect indicator A/B (active low). A low on this pin
indicates the modem has received a ringing signal from
telephone line.
VCC
33,44
I
Power supply input.
GND
12,22
O
Signal and power ground.
