Using Arduino Uno TX and RX pins

hello,

i needing regarding using arduino uno tx , rx pins. trying use serial connection pins on board without using usb port on board. instead, use miniusb/serial adapter website offers. possible? connect tx pin on uno tx pin on adapter , rx pin on uno rx pin on adapter or vice versa? there additional lines of code need add use these pins instead of usb port?

thanks.

sure, can that.
the ftdi basic referring to?
connect tx uno rx,  rx tx, gnd gnd, cts gnd, +5 +5, , dtr to  reset:
ftdi    uno
tx       rx
rx       tx
dtr     reset
+5       +5
gnd    gnd
cts     gnd

in void setup(), add:
serial.begin(speed, such 9600);  // library takes care of defining d0, d1 you. data format used 1 start bit, 8 bits, no parity, 1 stop bit (8n1)

in void loop(), use commands such as

if (serial.available() >0){ //take action when byte received
incomingbyte = serial.read(); // read byte
}
and
serial.print (your_outgoing_byte);  // data go out serial monitor displayable character
or
serial.println (your_outgoing_byte); // data "carriage return"
or
serial.write (your_outgoing_byte);  // data goes out as-is, may not displayable character in serial monitor.
