I'm not an expert myself on this thing but as I had the same
question in a similar course some time ago, I was advised to use tinufugue
(tf). To be honest, I didn't realise much difference in the way I was
connecting to BioMOO with tf in comparison to telnet. They were both
working fine for me. Maybe because I never carried out too much demanding
things within the BioMOO environment. Anyway, if you want, have a look at
the above mentioned client as well.
