| When you start Windows Telent, don't give it the IP address of the terminal server. When the MS Telnet prompt comes up, use the command 'unset CRLF' to stop it from sending a CR adn an LF when you hit Enter. Then use the open command to call the terminal server. Below is a sample to talk to a Term Server at 10.10.10.22, using port 2001 which in the Case of our MRV's and Micro-Annexes would translatoe to serial port 1. The annoying part is, not all machines have to use the unset command. Somewhere there has to be documentation on which versions of windows telnet do this and why.
c:\telnet
