Octal. "chmod 0666 /dev/ttyACM0".
Those two commands are equivalent. The leading digit is optional, and
not an indication that the number is octal. All numeric mode
descriptions are octal, with or without a leading 0. The leading digit
may be used to specify additional permission. If present, it "selects
the set user ID (4) and set group ID (2) and restricted deletion or
sticky (1) attributes."
