While on the topic ('Talk'), I would like to know if the *Ultrix* talk
is based on socket() and related calls, or something else?
I ask because on an Ultrix host I'm working with, a call for 
socket(AF_INET, SOCK_STREAM, 0) [or SOCK_DGRAM] fails with
"permission denied". but the talk (w/o suid root) works...

Also, Could someone please post some examples of sys v streams??
(or send to me directly if they're lengthy ones, thanks...)  In particular,
How can one achieve what the bsd's socket()/bind()/accept()/connect()
does, using streams (to send datagrams into the Internet)??
