[SOLVED] Startup help please. Reading serial data from a pin.

Projects General Guidance

Graynomad:
Why not make life easy and move the wires to some unused pins? After all that's the main purpose of Software Serial.

Tried all other pins.
No change......

Okay........ Update.

I have data coming in.
After alternating between all available pins with no correct results, I tried several other libraries.
Finally 'AltSoftSerial' did the trick. However, only on pin 13 and no other pin.

Here is the code I'm using with the data coming in pin on D13.

#include <AltSoftSerial.h>
#include <String.h>

AltSoftSerial altSerial;

void setup() {
  Serial.begin(4800);
  Serial.println("AltSoftSerial Test Begin");
  altSerial.begin(4800);
  altSerial.println("Hello World");
}

void loop() {
  char c;
  String s;
  
  if (Serial.available()) {
    c = Serial.read();
    
    altSerial.print(c);
  }

  if (altSerial.available()) {
    c = altSerial.read();
    s = String(c,HEX) + " ";
    Serial.print(s);
  }
}

See the result

So.... I get data to handle in my Arduino. Step one is a fact. Now I can move on.
All you guys, thank you very, very much for thinking along with me.

BTW
The conversion to hex is just to visually see the same characters as I see in my terminal program.
That works, though '00' will be represented as "0" and 'A3' will become "ffa3"..........
The first I can understand, but how come each value starting with 'A' or higher will get 'ff' in front?
(Or do I have to start a new topic for this?)
