T)oggle.  Allows you to switch settings on RBBS.  If on, toggles to off.
If off, toggles to on.  The sub-options in TOGGLE are:

A)utodownload.  Whether to use auto-downloading.
B)ulletin.  On logon ask if to read bulletins only when new, or always.
C)ase change.  Display characters in upper case only or upper/lower.
F)ile.  On logon give option to download new files, or not.
L)ine feeds.  Insert line feed after each carriage return, or not.
N)ulls.  Insert 5 nulls between carriage-return & line feed, or not.
X)pert.  Show menus or only single command line.
!)bell.  Beep whenever RBBS expects input or be silent.

TIPS:
A)utodownload.   A downloading enhancement that allows RBBS-PC to tell the
   caller's software what to do at the end of each download.  Packages that
   support "autodownloading" include some variants of PC-Talk and Pibterm.

B)ulletin.  RBBS-PC will skip bulletins automatically unless there are new
   bulletins since your last logon.  If you want option to read bulletins
   on log on everytime, whether or not there is anything new, turn this
   option off (check rather than skip new bulletins).  The sysop can
   disable this option for all users, forcing the bulletins to be always
   reviewed.

C)ase change:  Most home computer systems can display both upper and lower
   case letters but some computers only display upper case.  The "C"
   command toggles or alternates between "UPPER CASE ONLY" and "UPPER CASE
   and lower case."

F)ile.  RBBS-PC will give you the option to review files new since your
   last logon right after giving your name and password.  If you want to
   wait until after you have check bulletins and mail before reviewing
   files for downloading, turn off this option.  The SYSOP can disable this
   option for all users.  This option makes it fast and easy to check for
   new software on RBBS-PC.

N)ulls: Nulls put a delay at the beginning of each line that RBBS-PC sends
   to your system.  Entering "N" will toggle or alternate nulls on and off,
   as you choose.  The purpose of using nulls is to allow a receiving
   device such as a teletype that prints to have enough time to move the
   print head from the right-most column back to the first column in order
   to begin printing the next line being sent. Most of us go through our
   whole lives without the need for nulls, however.  Normally leave nulls
   off, because it will increase the characters transmitted.

X)pert: RBBS-PC operates in two modes.  Novices get verbose menus, more
   detailed explanations, and extra warnings.  Experts get succinct command
   prompts having only the first letter.  The novice mode makes it easier
   to learn how to use RBBS-PC but is slower.  Simply press the  "X" key to
   alternate or toggle between X)pert and Novice modes.  It is recommended
   that callers use the novice mode until they become comfortable with
   RBBS-PC's commands.

!)Prompt bell:  An auditory reminder (beep) to tell you when the computer
   is awaiting your input.  Some find it useful, some tiresome.   The
   prompt bell is particularly helpful when downloading (or uploading)
   large files, or a long list of files. You can leave your PC and will be
   "called back" when RBBS-PC has finished sending (or receiving) data.
   Just remember not to wander out of earshot! If you leave RBBS-PC
   unattended, you will be automatically logged off after 3 minutes.
