-// On ESP8266:
-// SoftwareSerial loopback for remote source (loopback.ino), or hardware loopback.
-// Connect source D5 (rx) to local D8 (tx), source D6 (tx) to local D7 (rx).
-// Hint: The logger is run at 9600bps such that enableIntTx(true) can remain unchanged. Blocking
-// interrupts severely impacts the ability of the SoftwareSerial devices to operate concurrently
-// and/or in duplex mode.
-// On ESP32:
-// For software or hardware loopback, connect source rx to local D8 (tx), source tx to local D7 (rx).
