     CON(1)                                                     CON(1)

          con, telnet, hayes, cu, rx, xms, xmr - remote login,
          execution, and XMODEM file transfer

          con [ -dCrv ] [ -l [ remuser ] ] [ -c cmd ] net!machine

          telnet [ -dCr ] net!machine

          hayes [ -p ] number [ device ]

          cu number

          rx [ -n ] net!machine [ command-word ... ]

          xms file

          xmr file

          Con connects to the computer whose network address is
          net!machine and logs in if possible.  With no options, the
          account name used on the remote system is the same as that
          on the local system.  Standard input and output go to the
          local machine.

          Options are:

          -l   with an argument causes remuser to be used as the
               account name on the remote system.  Without an argument
               this option disables automatic login and a normal login
               session ensues.

          -C   forces cooked mode, that is, local echo.

          -c   runs cmd as if it had been typed as a command from the
               escape mode.  This is used by cu.

          -v   (verbose mode) causes information about connection
               attempts to be output to standard error.  This can be
               useful when trying to debug network connectivity.

          -d   causes debugging information to be output to standard

          -r   suppresses printing of any carriage return followed by
               a new line.  This is useful since carriage return is a
               printable character in Plan 9.

          The control-\ character is a local escape.  It prompts with

     CON(1)                                                     CON(1)

          the local machine name and >>>.  Legitimate responses to the
          prompt are

          i    Send a quit [sic] signal to the remote machine.
          q    Exit.
          b    Send a break.
          .    Return from the escape.
          !cmd Run the command with the network connection as its
               standard input and standard output.  Standard error
               will go to the screen.  This is useful for transmitting
               and receiving files over the connections using programs
               such as xms.

          Telnet is similar to con, but it uses the telnet protocol to
          communicate with the remote machine.

          Hayes dials a number using the Hayes modem protocol.  Option
          p uses pulse dialing rather than the default tone dialing.
          If specified, device is the file opened for the call.  The
          default is /dev/eia0.

          Cu is a shell script that uses hayes and con to connect to a
          machine via a modem.  If the machine is equipped with a
          local modem, it is used.  Otherwise, the call is placed
          through Datakit.

          Rx executes one shell command on the remote machine as if
          logged in there, but with local standard input and output.
          Unquoted shell metacharacters in the command are interpreted
          locally, quoted ones remotely.  The assignment REXEC=1
          appears in the remote environment.

          Network addresses for both con and rx have the form
          network!host.  Supported networks are those listed in /net.

          The commands xms and xmr respectively send and receive a
          single file using the XMODEM protocol.  They use standard
          input and standard output for communication and are intended
          for use with con.

          rx kremvax cat file1 >file2
               Copy remote file1 to local file2.

          rx kremvax cat file1 '>file2'
               Copy remote file1 to remote file2.

          Under rx, a program that should behave specially towards
          terminals may not: e.g., remote shells will not prompt.
          Also under rx, the remote standard error and standard output
          are combined and go inseparably to the local standard out-
