I’m trying to use vi, but instead of clearing the screen and allowing me to view my file, it jumbles the file and none of the commands react as expected; or in more general terms, “In console (command line) mode, I’m trying to use any application that requires use of the full screen (SunVTS, vi, etc) and when I launch it, it doesn’t correctly show the entire screen.

A: Depending on which Sun machines you are connecting, you will need a certain type of null modem cable suited to that machine. Most older Sun machines (UltraSPARC II and some III) will require a DB25 male connector on the end. Newer ones (some UltraSPARC III and IV) will need RJ-45 serial connections.
A: Depending on which Sun machine you are connecting to, you will need a specific type of null modem cable suited to that machine. Most Sun UltraSparc II-class machines will require a DB25 male connector on the Sun end. Sun’s UltraSPARC III-class and higher machines have a healthy mix of DB25 and RJ-45 connectors. Plus […]

You can seriously disable your system and render it unusable by incorrectly using this information. Heck, even if you use it correctly I can’t guarantee I didn’t make a mistake while writing it. In short, do not use these tutorials/commands/information on a live, production system.
