help configuring telnet

How can a telnet client be configured to:
1. not operate in line mode,
2. not echo characters locally,
3. not translate a carriage return to CRLF, and
3. and not require a telnet server on the other end to negotiate options?

I know number 3 sounds strange, but I'm trying to use telnet to
communicate with a NET232 device from GridConnect.com. The
NET232 device is an ethernet-to-serial converter that I use as a passthru
to access the serial port of another device, and I don't think the NET232
really has a telnet server running in it. It works fine when I use a
HyperTerminal's TCP/IP connection mode from a Windowswmachine,
but I need access from a Linux box (SUSE 10.0).

Is there an alternative to telnet that implements a very simple TCP/IP
chat session on a specifiable port number?

Thanks,

netcat will probably do what you want. Depending upon the build, it has
a -t switch to do telnet negotiation, but otherwise it doesn't. Since
it's not a terminal program, it doesn't echo, translate, or any of those
other things.
