First, you're using release 1.0 which specifically does not support block
mode through telnet. You need release 1.1 which does include this
support.

Second, a Sun does not support HP block mode and the telnet server is
not a terminal emulator so the fact that it can handle block mode does
not mean you can use it on your Sun. Basically, if you can connect your
Sun (or whatever) directly to an HP3000 and run block mode then
you'll be able to use it via telnet. However, if not then telnet does
not in any way change that. You have to remember that block mode happens
between the application program running on the 3000 and the terminal. It 
is the terminal that understands block mode, not the telnet server.

Telnet 1.1 doesn't actually understand block mode the way an application
using block mode does. The telnet sever understands block mode in how
it communicates with the pseudo-terminal driver. For example, the terminal
type request, etc.

What you can do are:

Connect a hp terminal to your Sun and use that instead of the Sun
console. Remember, the Unix termcap on the Sun doesn't come into play
here so you have to have an HP terminal or an emulator. When I left
Sun (2/88) I was not aware of any HP terminal emulation for a Sun.
