Text Mode vs. Binary Mode

• Text mode will process data by lines, and it won't escape/unescape chars
  • If you want to specific the linebreak to be send, use flag -linebreak, avaliable values are:
    cr: use \r
lf: use \n (default as well as fallback)
    crlf: use \r\n
• Binary mode will process input data by lines with space splited numbers as bytes, and output data by per buffer.
  • The length of the buffer can be set use flag -buffer / -B
  • If the data cannot fill over the buffer, it will be print anyway
  • The base prefix is allowed, and the default base is 16 (0b: 2, 0o: 8, 0x: 16)
  • If you want to send literary text under the binray mode, just add prefix char ! in front of the line
