i have hyperterminal (as well as secureCRT) but i don't know how to connect with them. i tried a com1 session with HTerminal and it counted up the connected clock but the cursor just hung in the upper left ... nothing happened and it didn't respond when i typed "ls" for example

Assuming you set the correct options in hyperterminal, then the problem lies with the COM port, the PC's settings, or the cabling. You should be able to see what you're typing at the shell prompt.

If Hyperterminal won't work then the logo editor won't work either, as they use the same communication method.

Try it on a different computer and see if it works.
