              Cux allows communication with another system.  It  manages
              an interactive conversation with possible transfer of text
              files and i/o redirection.

              The program requires two serial ports.  Input from tty and
              the  other  port is managed by AST service routines.  This
              provides for up to 1200 baud communication  through  a  DZ
              asynchronous multiplexer.

              To connect to another system, run cux and then dial up the
              other  computer.   At  this  point, anything typed at your
              terminal is transmitted to the remote system.  You are ef-
              fectively talking with the other system.

              Once a connection is made, lines beginning with  control-W
              (^W) have special meanings.

              Cux interprets the following:

              ^W.                 terminate the conversation.
              ^W^Z                terminate the conversation.
              ^W<[:]file          send the contents of 'file' to the re-
                                  mote  system  as  though  typed at the
                                  terminal.
              ^W>[>][:]file       divert output to the named file.
              ^W!                 escape temporarily to  enter  commands
                                  to the local system.
              ^W%take from [to]   copy file 'from' (on the  remote  sys-
                                  tem) to file 'to' on the local system.
                                  If 'to' is omitted, the 'from' name is
                                  used both places.
              ^W%put from [to]    copy file 'from' (on local system)  to
                                  file  'to'  on  the remote system.  If
                                  'to' is omitted, the  'from'  name  is
                                  used both places.
              ^Wx                 toggle 'start'  and  'stop'  character
                                  transmission   to  the  other  system.
                                  (xon-xoff protocol observed)
              ^We                 toggle   the   echo   of    characters
                                  transmitted   to  the  remote  system.
                                  This can be used  to  override  silent
                                  diversion.

              ^W^W                send the character '^W'
              ^Wa                 abort 'put' or '<'
              ^Wh                 print any available help text

              The receive process handles output diversions of the  fol-
              lowing form:

              ^W>[>][:]file

              for zero or more lines to be written to 'file' or 

              ^W>

              to terminate the diversion.

              In any case, output is diverted (or appended, if  '>>'  is
              used)  to  the  file.   If  ':'  is used, the diversion is
              silent, i.e., it is written only to the file.  If  ':'  is
              omitted,  output  is  written  both to the file and to the
              standard output.  The trailing '^W' terminates the  diver-
              sion.

              Conditional compilation permits tailoring the program to a
              particular  operating  system.   Refer to cu.h for further
              details.

              Because operating system  service  is  required  for  each
              character entered and received, throughput may greatly de-
              teriorate when the system is under heavy (or even  normal)
              use.
