VERSION
   to-talk 1.1, 25 Sep 1995


ABSTRACT

   An "old talk" client and server.

   This is a hacked version of NetBSD's [n]talk & [n]talkd

   The programs were modified to conform to the protocol used 
   by the OLD (BSD4.2) talk server and clients
   i.e. those using port 517/udp.

   to-talk-1.1 has successfully been tested on linux-1.3.29/i586.
   It was able to communicate locally to itself as well as to 
   remote native talks on
        SINIX-N 5.41    RM400   R3000
        SunOS   4.1.3   sun4m   sparc
        SunOS   5.4     sun4m   sparc
        TOS64M  4.1.01  i88_hfx TARGON/35-M50
        SINIX-L 5.41    i386    MX300
        unisys  4.0     i386    386/AT

SYNOPSIS

   to-talk user[@host] [tty]

   inetd.conf:
   talk    dgram   udp     wait    root    /usr/local/sbin/to-talkd to-talkd



INSTALLATION NOTES

   to-talkd requires to be entered to /etc/inetd.conf.
   "make install" automates this.



INSTALLATION FROM SOURCE CODE

   Under Linux, follow these steps:

   unpack:      tar xvfz to-talk-1.0.src.tar.gz
   compile:     cd to-talk-1.0 ; make
   install:     su root -c "make install"



INSTALLATION FROM BINARY CODE

   Under Linux, follow these steps:
   (Note: Binary version requires libcurses.so.0.1.2 & libc.so.4.6.27)

   unpack:      tar xvfz to-talk-1.0.bin.tar.gz
   install:     cd to-talk-1.0; su root -c "make install"



BUGS

  to-talk-1.0 cannot talk to new talk daemons (518/udp).
  to-talk-1.0 cannot talk to the following old talk daemons:
        ULTRIX  4.3     RISC            
        (this is not really an old talk; use new talk instead!)
