##### Conventions

Following are the conventions used in this document:

- Special fonts
  - A special font is used for any input you need to enter. For example,

    `mkpconn`

  - Optional parameters will be displayed within square brackets. For example,

    `ditty [-a] [altpin]`

    The square brackets themselves are not actually part of the command, and should not be entered.

  - Variables will be displayed in italics. For example,

    `stty-digi ttyname`

    Substitute an appropriate TTY name for ttyname in the above command.

  - A vertical bar character (|) is used to denote a choice (logical "or"). For example,

    `set flow=on|off`

    The above command would be entered as either

    `set flow=on` or `set flow=off`.

- Keys and titles of dialog boxes, indexes, menu bars, windows, etc. appear exactly how they appear on the keyboard or on the screen.
- The word, Choose, can mean Click, Point, Select, Hit, Press and so on.
