In this section, we will use the term "MIT Zephyr users" to indicate people zephyring using their Athena accounts. Users who are not "MIT Zephyr users" include (for example) Zephyr users at Carnegie-Mellon University.

To set or change your exposure, type (for example):
In this example, your exposure is changed to "
athena% zctl set exposure realm-announced
realm-announced". This allows MIT Zephyr users (but not non-MIT Zephyr users) to
zlocateyou, and announces your login or logout to anyone who has your username in their .anyone file. Many users find the "
realm-announced" exposure level (which is not the default) to be the most useful setting.
The exposure setting is permanent until you change it again.
By default, fallback is disabled, so you cannot to receive zephyrgrams while on a dialup. While you can manually activate Zephyr by typing:
However, it may be more convenient to have Zephyr always automatically "fall back" to text-based mode when X is unavailable. To cause this fallback, type:
athena% zwgc -ttymode
After doing so, text-based Zephyr will always be activated on dialups, or any other text-based terminals. The one downside is that anything you are doing on the dialup will be interrupted by incoming zephyrgrams overwriting the screen. Pressing Ctrl+L will usually refresh the screen.
athena% zctl set fallback true

The most important command to know in owl is '
athena% add ktools
h', which brings up the online help. Here is quick summary of the other commonly used keys:
|<up> <down>||move up and down between zephyrgrams|
|<left> <right>||scroll around within long zephyrgrams|
|z||send a zephyrgram (you can use |
|r||reply to current zephyrgram|
|d||mark current zephyrgram for deletion|
|x||delete marked zephyrgrams|
|l||show list of online users (equivalent of znol)|

Note that you must have Kerberos tickets before WinZephyr will start. If you have not done so already, get Kerberos for Windows from the same software download page. After installing it, run Leash32 to get tickets.
The top of the Sender box has three text boxes, each for one of the three components of zephyr triplets. To send zephyrgrams to an individual user, simply type the username in the RECIPIENT box, and leave the other two boxes blank (or set them to MESSAGE and PERSONAL). To send zephyrgrams to a class or instance instead, type the name of the class or instance in the correct box, and leave the others blank.
After having specified the recipient, type your message in the large MESSAGE text box. You may find the checkbox marked "Auto" helpful, so that your text is auto-cleared after you send zephyrgrams, and so that you don't accidentally send duplicate zephyrgrams.
If you receive a zephyr and wish to reply, you can also click the "Reply" link that shows up, which will also bring up the sender box with the recipient boxes automatically filled in. If the message was sent to a class or instance, WinZephyr will default to responding to the same class or instance. Replying to personal zephyrgrams will by default respond to the original sender.
znolcommand, right-click the blue Z and choose ZNOL. Some users have experienced problems with this, however, and WinZephyr will instead list a few users and stop. You may want to SSH into a dialup machine and run znol there instead.
