DESCRIPTION

       This  package  provides  the  most primitive commands for receiving characters to a terminal. They are in
       essence convenient wrappers around the builtin commands read and fileevent.

       ::term::receive::getch ?chan?
              This command reads a single character from the channel with handle chan  and  returns  it  as  the
              result of the command.

              If not specified chan defaults to stdin.

              It  is  the  responsibility  of  the  caller  to  make  sure  that  the channel can provide single
              characters.  On  unix  this  can  be  done,  for  example,  by  using  the  command   of   package
              term::ansi::ctrl::unix.

       ::term::receive::listen cmd ?chan?
              This  command sets up a filevent listener for the channel with handle chan and invokes the command
              prefix cmd whenever characters have been received, or EOF was reached.

              If not specified chan defaults to stdin.

              The signature of the command prefix is

              cmd process string
                     This method is invoked when characters were received, and string holds them for processing.

              cmd eof
                     This method is invoked when EOF was reached on the channel we listen on.  It  will  be  the
                     last call to be received by the callback.

       ::term::receive::unlisten ?chan?
              This command disables the filevent listener for the channel with handle chan.

              If not specified chan defaults to stdin.
