Print special characters via serial

Hi, I don't understand, how I should print a string with special characters.

I want to send a string with the software interface to another device.

The signs to be sent are: "=
and 1$

is this correct?
lap_counter_serial.print('"=');
or this
lap_counter_serial.print("1$");

Thanks for your help.

What happens when you try? What is the device? Different devices display characters differently.

Also, why do you consider "=" a special character? It seems pretty standard to me, it's on every keyboard and ASCII display I've ever seen.

This

lap_counter_serial.print('"=');

is not correct because single quote marks indicate a single character.

If you need to send a formatting character like (") then you use a standard C escape sequence. Look it up.

Your topic was MOVED to its current forum category as it is more suitable than the original

  Serial.print("\"=");
  Serial.print("1$");

Thanks.

The escape sequence might work.

It's guaranteed to work by the C/C++ language standard.
