Description
     -----------

     DW Host normally monitors the modem  and upon detecting a ring  answers
     the call while adjusting to the  caller's baud rate.  Speeds of  19,200
     bps down to 300 bps  are supported with the following  comm parameters:
     8 data bits, no parity, 1  stop bit.  Upon successful connect,  DW Host
     greets the caller with a one-line message of your choosing and requests
     entry of a password, also of your choosing.  If the correct password is
     supplied and the callback mode is not in effect, DW Host will  transfer
     control  of  the  next  part  of  the  communications  session to other
     software.  Depending on the configuration option chosen, the caller may
     be dropped  to the  DOS level  (with a DOORWAY command line having been
     invoked to support continued communications).  Or a caller may next see
     another communications application,  such as a  BBS-like package, or  a
     menu of programs that might be run (using the Doorway munu capability).
     If  the correct  password is  not given  to DW Host  in three attempts,
     DW Host hangs up and recycles.

     For enhanced security against unauthorized access the callback feature
     is available.   If  the callback  mode is  in effect  when the correct
     password is given, rather than  give the caller immediate access,  the
     program  disconnects  the  caller  and  dials  the  telephone   number
     specified in the configuration data.  Access is granted only if  there
     is  a  successful  connect  at  that  number.    DW Host makes up to 3
     attempts  to  establish  a  connect  (it  calls  a 2nd and 3rd time at
     intervals  of  1  minute  if  no  answer,  a  busy signal, or no modem
     connect).  If no  connection is made on  the 3rd attempt, the  program
     recycles and sets up to await another call.

     If access is  granted to the  DOS level on  the host machine  (through
     DOORWAY), virtually all DOS commands  may be executed and so  may most
     other programs which do not use bit mapped graphics.  A program called
     DWXFER  supports file  transfers while in DOS.  It is included in this
     ZIP.  You might also like to try Chuck Forsberg's DSZ  for Zmodem file
     transfers, rather than the older protocol provided by DWXFER (although
     DWXFER is simpler to use).

     A log of call activity (a file called DW.LOG) is created by DW Host so
     that any attempts of unauthorized access to your system may be  noted.
     Calls  accepted  (and   normal  logoffs),  rejected   calls  (password
     failures), and other  connects not resulting  in access to  the system
     (hang  ups  at  the  password  prompt  and  3-minute timeouts awaiting
     password entry) are all recorded in this text file.  The file includes
     the date and time of each call  and how each ended.  It can  be viewed
     using the the DOS TYPE command.  It may be deleted at any time  (using
     DOS ERASE or DEL)  and the program will  start a new one  whenever the
     next entry is to be made.

     When DW Host  is awaiting  a call,  a display  including the  date and
     time, some key setup information, and present DW Host status is shown.
     A screen blanker turns off the screen if there is no keyboard activity
     within a 2-minute span.  Striking  any key restores the display.   The
     display  also  is  toggled  on  and  off  by hitting F9.  F10 presents
     information about the program.  F3 allows access to the  configuration
     screen where various DW Host setup options may be specified.  F1 or F2
     cause DW Host to terminate.   F1 leaves the  telephone line in a  BUSY
     state (modem offhook) while F2 leaves the modem onhook.
