Description
3.3 V power source for the demo board .
Request To Send – Low true input. Used for RTS/CTS flow control and V.23
transmission control. Controlled by the Kn command.
Clear To Send – Low true output. Used for RTS/CTS flow control and to
indicate carrier is being sent in V.23 mode. Controlled by the Kn command.
Data Set Ready – Low true output. Indicates the modem is present and
ready for use.
Data Carrier Detect – Low true output. Indicates a carrier is being received.
Controlled by the Cn command.
RI ng – Low true output. Indicates a valid ring signal is being received. Goes
low for the duration the “ring” result code is being sent on RXD.
Transmit Digital Input. Pin used as the digital data input for commands and
data transmission.
Data Terminal Ready – Low true Input. Pin used by the terminal to control
certain actions of the modem, such as return to command mode, terminate
call, V.23 turnaround, reset, and power down.
Receive Digital Output. Pin used as the digital data output for echoing
commands and for data reception.
Demo board ground.
