non-blocking sockets

[conrad]

I'm automating some things that have to
do with checks on a cisco 3750 switch.

Using the Socket class, it seems
that the socket is blocking because
I stall at the prompt for "Username"
when I connect to the switch. Is this
correct?

I was looking into Java's support for
non-blocking sockets and it seems
to have been introduced in J2SE 1.4.

If this is the case, what was used
prior to this?

That is correct.

You need to use NIO to do non-blocking and that was
introduced in 1.4.

Before that you had to have a thread per blocked read.

BTW, that is still the easiest paradigm for a small
number of blocked reads.
