Hi Murray,
Just looking at the screenshot I would suggest you be very careful when typing inside a Windows telnet session. Windows telnet sessions have poor editors responding incorrectly to white spaces, especially back spaces. The "record/b/b/b/b/b/b" in your screenshot only means you typed record, typed more, and then you pressed the back space 6 times. This would be translated to a command like record/b/b/b/b/b/b, which is obviously foreign to the EMS server. Interestingly, Linux telnet session editors work great!
I would suggest you type in the commands you want to use in a separate editor, and then paste each one to the telnet session.
Try your commands again. And let us know how it goes.
Thanks.
