NAME
bcd, ppt, morse - reformat input as punch cards, paper tape or morse code
SYNOPSIS
bcd [string ...]
ppt [-d [-b] | string ...]
morse [-d | -s] [string ...]
DESCRIPTION
The bcd, ppt, and morse commands read the given input and reformat it in
the form of punched cards, paper tape, or morse code, respectively. Ac-
ceptable input are command line arguments or the standard input.
Available options for ppt:
-d [-b]
The -d option for ppt decodes paper tape on the standard input
back to ASCII. Unprintable characters are visually encoded with
vis(3) unless the -b flag (binary) is also specified. A lowercase
'x' is printed for undecipherable input lines.
Available options for morse:
-d The -d option for morse decodes dot-dash morse
(as generated by using the -s option) back into text. A lowercase
'x' is printed for undecipherable input; otherwise, text is re-
turned uppercase. If the morse to be translated is given on the
command line, it should be preceded by '--' to keep it from being
mistaken for options.
-s The -s option for morse produces dots and dashes rather than
words.
