Talk for Sys V

[Nigel Holder Marconi]

   Oops - I made the age old mistake of signed and unsigned chars.  On
my machine there is no problem (GEC 63 (what I here you ask) running 5.2).
A few of you are having such problems so here is the fix in diff
format which I hope works since I can't test them properly on my machine
(talk still works though).
