Description

I'm requesting support for .findMulti();

Steps To Reproduce Problem

Run code in any IDE

Hardware & Software

Arduino IDE version: 1.8.19
Version info & package name: Arduino AVR Boards 1.8.6
Operating system & version: MacOS 13.1 (22C65), ARM APPLE SILICONE

Arduino Sketch

#include <Arduino.h>
#include <AltSoftSerial.h>

AltSoftSerial TestSerial;

void setup()
{
  TestSerial.findMulti();
}

void loop()
{
  // put your main code here, to run repeatedly:
}

Errors or Incorrect Output
