==Functions==

===read()===
Serial.read() returns an unsigned byte by assignment.
===write()===
Serial.write() returns a size_t of the number of bytes written.
====write(byte val)====
This writes a binary 8-bit val.
====write(byte array[])====
This writes the contents of the array as 8-bit binary until the NULL terminator is found (C String)
====write(byte array[], size_t len)====
This writes len-number binary bytes from array
===print()===
Serial.print() creates ASCII/human readable text, from any datatype, depending on type. This is not guaranteed to display binary. Defaults to DEC unless specified explicitly (BIN, OCT, DEC, HEX).
====print(byte)====
This transforms the byte into a string of decimal digits and then writes them over serial.
====print(short|int|long|float)====
This transforms these respective data types into a string of human readable numbers that are then sent over serial.
====print(byte, HEX)====
This transforms the byte into either a one or two character string of 0-9, A-F and writes these to the serial.
====print(int array[])====
This prints strings of decimal values, without whitespace, to the serial
====print(char array[])====
This prints a string as symbols without checking that they are printable (can be binary too)
===println()===
Passes identical parameters to print() and then prints a CR/NL to the serial.
