OK, so I wrote a telnet version and that works, but now we are migrating to SSh and I have (attempted) to modify it to figure out which to use, and be able to use SSH. So far, it works with telnet capable devices, buy still tries to SSH to them as well, and doesn't work with SSH devices. So, technically, it does nothing more than the original telnet script... Hmm.... Anyway, am I missing something small or am I completely off base and need to RTFM?
